David Enskog
Quick Summary
David Enskog was a Swedish scientist who made significant contributions to the kinetic theory of gases. His work, along with that of Sydney Chapman, was crucial in solving the Boltzmann equation, which describes how molecular collisions and external forces alter the velocity distribution of gas molecules. This advancement allowed for more accurate calculations of gas transport coefficients, improving upon earlier "mean free path" theories. Enskog's contributions were essential for developing a more sophisticated and mathematically rigorous understanding of gas behavior, particularly in non-equilibrium states.1

gasThermal diffusion…was predicted in 1911–12 by David Enskog in Sweden and independently in 1917 by Sydney Chapman in England, but the validity of their theoretical results was questioned until Chapman (who was an applied mathematician) enlisted the aid of the chemist F.W. Dootson to verify it experimentally.
