Ag. Konstandopoulos et De. Rosner, INERTIAL EFFECTS ON THERMOPHORETIC TRANSPORT OF SMALL PARTICLES TO WALLS WITH STREAMWISE CURVATURE .1. THEORY, International journal of heat and mass transfer, 38(12), 1995, pp. 2305-2315
We study the combined action of particle inertia and thermophoresis in
boundary layer aerosol flows over surfaces with streamwise curvature,
in the limit of small particle Stokes number, Stk, when the interacti
on between these two transport mechanisms is expected to be most signi
ficant. The governing dimensionless parameter controlling inertial eff
ects is found to be Stk . Re-x(1/2), which can be large enough to caus
e dramatic changes in deposition rates even when Stk << 1, due to the
largeness of the streamwise Reynolds number, Re-x in boundary layer fl
ows. Predictions are presented for concave/convex surfaces either 'col
der' or 'hotter' than the mainstream.
