Suid-Afrikaanse Akademie Vir Wetenskap En Kuns
The Suid-Afrikaanse Akademie vir Wetenskap en Kuns (SAAWK) (literally ''South African Academy for Science and Arts'') is a multidisciplinary organization dedicated to promoting science, technology and the arts in Afrikaans, as well as promoting the use and quality of Afrikaans. The Hertzog Prize is awarded annually by the academy for high-quality literary work, while the Havenga prize is awarded annually for original research in the sciences. Origin The initiative for the founding of the SAAWK came from General J. B. M. Hertzog who championed the Dutch-Afrikaans language. He suggested ''"dat een lichaam in 't leven worde geroepen ter bevordering van de Hollandse taal en letteren in Zuid-Afrika"'' (that one organisation be established to promote the Dutch language and literature in South Africa). On 2 July 1909, the first 30 members of the body gathered to form the ''"Zuid-Afrikaanse Akademie voor Taal, Letteren en Kunst"'' (South African Academy for Language, Literature and ...

Burke–Schumann Flame
In combustion, a Burke–Schumann flame is a type of diffusion flame, established at the mouth of the two concentric ducts, by issuing fuel and oxidizer from the two region respectively. It is named after S.P. Burke and T.E.W. Schumann, who were able to predict the flame height and flame shape using their simple analysis of infinitely fast chemistry (which is now called as Burke–Schumann limit) in 1928 at the First symposium on combustion. Mathematical description Consider a cylindrical duct with axis along z direction with radius a through which fuel is fed from the bottom and the tube mouth is located at z=0. Oxidizer is fed along the same axis, but in the concentric tube of radius b outside the fuel tube. Let the mass fraction in the fuel tube be Y_ and the mass fraction of the oxygen in the outside duct be Y_. Fuel and oxygen mixing occurs in the region z>0. The following assumptions were made in the analysis: * The average velocity is parallel to axis (z direction) of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
