Llewellyn M. K. Boelter
Llewellyn Michael Kraus Boelter (August 7, 1898 – July 27, 1966) was an American engineer, Professor of Mechanical Engineering at the University of California, Los Angeles, and founding Dean of its UCLA Henry Samueli School of Engineering and Applied Science.George J. Maslach, Stafford L. Warren & Joseph W. McCutchan.Llewellyn Michael Kraus Boelter, Engineering: Berkeley and Los Angeles in: ''1968, University of California: In Memoriam,'' University of California (System) Academic Senate. May 1968. p. 18-21 In the late 1920s Boelter came into prominence for by his work in the field heat transfer, for which he had investigated heat transfer in the automobile Radiator (engine cooling), radiator of the tubular type. F. W. Dittus and Boelter proposed "a convective heat transfer correlation for turbulent flows," which became known as the Dittus-Boelter equation. In 1957 he was awarded the ASME Medal.

Winona, Minnesota
Winona is a city in and the county seat of Winona County, in the state of Minnesota. Located in bluff country on the Mississippi River, its most noticeable physical landmark is Sugar Loaf. The city is named after legendary figure Winona, who some sources claimed was the first-born daughter of Chief Wapasha of the Dakota people. The population was 25,948 at the 2020 census. History The city of Winona began on the site of a Native American village named Keoxa. The seat of the Wapasha dynasty, Keoxa was home to a Mdewakanton band of the eastern Sioux. European immigrants settled the area in 1851 and laid out the town into lots in 1852 and 1853. The original settlers were immigrants from New England.Minnesota: A State Guide page 263 The population increased from 815 in December, 1855, to 3,000 in December, 1856. In 1856 German immigrants arrived as well. The Germans and the Yankees worked together planting trees and building businesses based on lumber, wheat, steamboa ...

Dittus-Boelter Equation
In thermal fluid dynamics, the Nusselt number (, after Wilhelm Nusselt) is the ratio of convective to conductive heat transfer at a boundary in a fluid. Convection includes both advection (fluid motion) and diffusion (conduction). The conductive component is measured under the same conditions as the convective but for a hypothetically motionless fluid. It is a dimensionless number, closely related to the fluid's Rayleigh number. A Nusselt number of value one (zero) represents heat transfer by pure conduction. A value between one (zero) and 10 is characteristic of slug flow or laminar flow. A larger Nusselt number corresponds to more active convection, with turbulent flow typically in the 100–1000 range. A similar non-dimensional property is the Biot number, which concerns thermal conductivity for a solid body rather than a fluid. The mass transfer analogue of the Nusselt number is the Sherwood number. Definition The Nusselt number is the ratio of convective to c ...

People From Winona, Minnesota
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

UCLA Henry Samueli School Of Engineering And Applied Science Faculty
The University of California, Los Angeles (UCLA) is a public land-grant research university in Los Angeles, California. UCLA's academic roots were established in 1881 as a teachers college then known as the southern branch of the California State Normal School (now San José State University). This school was absorbed with the official founding of UCLA as the Southern Branch of the University of California in 1919, making it the second-oldest of the 10-campus University of California system (after UC Berkeley). UCLA offers 337 undergraduate and graduate degree programs in a wide range of disciplines, enrolling about 31,600 undergraduate and 14,300 graduate and professional students. UCLA received 174,914 undergraduate applications for Fall 2022, including transfers, making the school the most applied-to university in the United States. The university is organized into the College of Letters and Science and 12 professional schools. Six of the schools offer undergraduate degre ...

American Institute Of Chemical Engineers
The American Institute of Chemical Engineers (AIChE) is a professional organization for chemical engineers. AIChE was actually established in 1908 to distinguish chemical engineers as a profession independent of chemists and mechanical engineers. As of 2018, AIChE had over 60,000 members, including members from over 110 countries worldwide.About the AIChE, Overview (from the AIChE website) Student chapters at various universities around the world have also been established throughout its history. The student chapters tend to focus on providing networking opportunities in both academia and in industry as well as increasing student involvement locally and nationally.

American Society For Engineering Education
The American Society for Engineering Education (ASEE) is a non-profit member association, founded in 1893, dedicated to promoting and improving engineering and engineering technology education. The purpose of ASEE is the advancement of education in all of its functions which pertain to engineering and allied branches of science and technology, including the processes of teaching and learning, counseling, research, extension services and public relations. ASEE administers the engineering technology honor society Tau Alpha Pi. History A full reading of the history of ASEE can be found in a 1993 centennial article in the Journal of Engineering Education. Founded initially as the Society for the Promotion of Engineering Education (SPEE) in 1893, the society was created at a time of great growth in American higher education. In 1862, Congress passed the Morrill Land-Grant Act, which provided money for states to establish public institutions of higher education. These institutions f ...

Radiator (engine Cooling)
Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plant or any similar use of such an engine. Internal combustion engines are often cooled by circulating a liquid called ''engine coolant'' through the engine block, and cylinder head where it is heated, then through a radiator where it loses heat to the atmosphere, and then returned to the engine. Engine coolant is usually water-based, but may also be oil. It is common to employ a water pump to force the engine coolant to circulate, and also for an axial fan to force air through the radiator. Automobiles and motorcycles In automobiles and motorcycles with a liquid-cooled internal combustion engine, a radiator is connected to channels running through the engine and cylinder head, through which a liquid (coolant) is pumped. This liquid may be water (in climates where water is unlik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
