FEATURES OF HEAT TRANSFER IN A FLAT POROUS MICROCHANNEL WITH THE SECOND ORDER SLIP BOUNDARY CONDITIONS

The results of the study heat transfer under forced convection in a flat porous microchannel taking into account boundary conditions slippage first and second order are considered.
 simulation showed that with decreasing porosity flow velocity central part slipping on wall decrease due to increase hydrodynamic resistance. Taking influence shows magnitude jump varies depending value parameter A2. decreases positive A2, negative - increases comparison case A2 = 0 (first conditions).
 Qualitatively similar effects second-order were also observed respect temperature profiles.
 calculation relative Nusselt number contributes intensification transfer.
 dynamics change coefficient an Knudsen indicates Prandtl leads improvement thermal interaction channel wall. analysis at small values (Pr ≤ 1) was not observed. At < lead number, whereas A2> normalized (boundary order).
