Most of the literature proposed analytical thermophoretic deposition models, either for laminar flow [4], for developing flow with empirical fit in certain range of Prandtl number and thermophoretic coefficients [5], and for laminar and turbulent flow under any Prandtl number, Pr, and thermophoretic coefficient, [K.
For slope flows, for example, the classical theory of Prandtl (1942, 1952) provides a basis for obtaining an analytical formulation for the near-surface wind speed profile, extended over the years to less constrained conditions [most recently, e.
