John Ffowcs Williams
John "Shôn" Eirwyn Ffowcs Williams (1935–2020) was Emeritus Rank Professor of Engineering at the University of Cambridge and a former Master of Emmanuel College, Cambridge (1996–2002). He may be best known for his contributions to aeroacoustics, in particular for his work on Concorde. Together with one of his students, David Hawkings, he introduced the far-field integration method in computational aeroacoustics based on Lighthill's acoustic analogy, known as the Ffowcs Williams–Hawkings analogy. Ffowcs was elected as a member into the National Academy of Engineering in 1995 for contributions to the theory of jet noise, and other aspects of aeroacoustics and hydrodynamics. Education and early life Born in Wales on 25 May 1935, Ffowcs Williams was educated at the Great Ayton Friends' School and Derby Technical College (now part of the University of Derby).Anon (2017) He served an engineering apprenticeship with Rolls-Royce before going to the University of Southam ...

Emeritus
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Protoc ...

Bachelor Of Science
A Bachelor of Science (BS, BSc, SB, or ScB; from the Latin ') is a bachelor's degree awarded for programs that generally last three to five years. The first university to admit a student to the degree of Bachelor of Science was the University of London in 1860. In the United States, the Lawrence Scientific School first conferred the degree in 1851, followed by the University of Michigan in 1855. Nathaniel Southgate Shaler, who was Harvard's Dean of Sciences, wrote in a private letter that "the degree of Bachelor of Science came to be introduced into our system through the influence of Louis Agassiz, who had much to do in shaping the plans of this School." Whether Bachelor of Science or Bachelor of Arts degrees are awarded in particular subjects varies between universities. For example, an economics student may graduate as a Bachelor of Arts in one university but as a Bachelor of Science in another, and occasionally, both options are offered. Some universities follow the Oxford a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Engineering Apprentice
An engineering apprenticeship in the United Kingdom is an apprenticeship in mechanical engineering or electrical engineering or aeronautical engineering to train craftsmen, technicians, senior technicians, Incorporated Engineers and Chartered Engineer for vocational oriented work and professional practice. Chartered Engineers are usually formed through a university degree programme at the Masters Engineering level and may undertake a short form of post graduate apprenticeship. A typical example is the apprenticeships formerly available at the British Thomson-Houston and English Electric companies at Rugby in England. Subjects covered included mathematics, engineering sciences, limits and fits, metallurgy, foundry technology, engineering drawing, design, materials science for engineering materials, metalworking by hand, operating machine tools, and basic features of engineering design. Also refer to apprenticeship and the UK and German section. Elite technical apprenticeships (4-6 ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxford University Press
Oxford University Press (OUP) is the university press of the University of Oxford. It is the largest university press in the world, and its printing history dates back to the 1480s. Having been officially granted the legal right to print books by decree in 1586, it is the second oldest university press after Cambridge University Press. It is a department of the University of Oxford and is governed by a group of 15 academics known as the Delegates of the Press, who are appointed by the vice-chancellor of the University of Oxford. The Delegates of the Press are led by the Secretary to the Delegates, who serves as OUP's chief executive and as its major representative on other university bodies. Oxford University Press has had a similar governance structure since the 17th century. The press is located on Walton Street, Oxford, opposite Somerville College, in the inner suburb of Jericho. For the last 500 years, OUP has primarily focused on the publication of pedagogical texts and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Great Ayton Friends' School
Great Ayton Friends' School (1841–1997) in Great Ayton, North Yorkshire, England, was an independent, co-educational, agricultural boarding school, run by the Religious Society of Friends (the Quakers). The school was situated on High Green on an estate of around . The River Leven (a tributary of the River Tees), ran through the school grounds and was bridged in several places. History Quakers in County Durham, having concern for children of disowned Friends who were not eligible for Quaker education, were searching for a suitable site to establish an agricultural school on their behalf. Unable to find a site in the preferred area of Bishop Auckland, Durham Friends sought the assistance of Thomas Richardson, a Quaker from Darlington who had come to live in Great Ayton on his retirement in 1830. In 1841 the school was established "for the maintenance of 36 boys and the same number of girls belonging to or connected with the Society of Friends; others are admitted at a c ...

Acoustic Analogy
Acoustic analogies are applied mostly in numerical aeroacoustics to reduce aeroacoustic sound sources to simple emitter types. They are therefore often also referred to as aeroacoustic analogies. In general, aeroacoustic analogies are derived from the compressible Navier–Stokes equations (NSE). The compressible NSE are rearranged into various forms of the inhomogeneous acoustic wave equation. Within these equations, source terms describe the acoustic sources. They consist of pressure and speed fluctuation as well as stress tensor and force terms. Approximations are introduced to make the source terms independent of the acoustic variables. In this way, linearized equations are derived which describe the propagation of the acoustic waves in a homogeneous, resting medium. The latter is excited by the acoustic source terms, which are determined from the turbulent fluctuations. Since the aeroacoustics are described by the equations of classical acoustics, the methods are called aero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computational Aeroacoustics
Computational aeroacoustics is a branch of aeroacoustics that aims to analyze the generation of noise by turbulent flows through numerical methods. History The origin of computational aeroacoustics can only very likely be dated back to the middle of the 1980s, with a publication of Hardin and Lamkin who claimed, that "'' ..the field of computational fluid mechanics has been advancing rapidly in the past few years and now offers the hope that "computational aeroacoustics," where noise is computed directly from a first principles determination of continuous velocity and vorticity fields, might be possible, ..'" Later in a publication 1986 the same authors introduced the abbreviation CAA. The term was initially used for a low Mach number approach (Expansion of the acoustic perturbation field about an incompressible flow) as it is described under EIF. Later in the beginning 1990s the growing CAA community picked up the term and extensively used it for any kind of numerical method d ...
