A solution is given, in hodograph coordinates, of the subsonic entry flow of a perfect gas in plane-parallel channels, in terms of the stream function. The particular solution and the full solution of the relevant equation are part-analytical and part-numerical. Results correspond to an approach velocity M*e = 0.5 and γ = 1.4. An error analysis is given, the results of which have general application in locating accurately the sonic line between regions of subsonic and supersonic flow. This analysis is applied in determining the steady, transonic choked flow of a perfect gas through a convergent channel. The methods of calculation can be applied in the design of engineering components, where flow structure and flow performance parameters are a basic requirement.

This study explores the flow of a second-grade fluid in divergent–convergent channel. The problem formulation is first developed, and then the corresponding nonlinear problem is solved by homotopy analysis method (HAM). The effects of different physical parameters on the velocity profile are shown. The numerical values of the skin friction coefficient for different values of parameters are tabulated.

The paper presents a numerical investigation of forced and mixing convection heat transfer and flow analysis of a passive heat exchanger inside clear (non-porous) and partially porous channels at different outlet area. Four discrete heat sources with uniform heat flux are simulated on the bottom wall of the channel. FORTRAN CFD code was developed and used to solve non-dimensional the governing equations for the fluid and porous media using finite volume method. The flow field and thermal analysis inside the channel are investigated across a wide range of Reynolds number (50 ≤ Re ≤ 300), Darcy number (10−2 ≤ Da ≤ 10−6), Richardson number (0 ≤ Ri ≤ 100) for 0.71 Prandtl number. The results show that the heat exchanger with partially porous convergent channel provides superior heat source cooling which leads to develop the macro and microelectronic devices.
