| Summary: | a square straight channel. Grid-independent solution and for post-processing the results. For solving the and the converged velocity field was input to the are observed at certain regions in the serpentine because of the thinner thermal boundary layer. The by studying the plotted flow-field velocity vectors in channel with the highest Reynolds number (Re=200). channels which are explained by the impingement channels, which have applications in heat-exchangers, condition. The post-processing module obtained the convection problem, the flow field was solved first developed to solve this problem. Modules were made for different planes. different Prandtl numbers ( 0.7 and 7.0 for air and enhancement of heat transfer mechanism was explained facilitated the application of periodic inverted flow field, colocated grid formulation was used as friction factor increased as the amplitude of the generating rids in the domain, for valving the flow heat transfer coefficients than the low Pr (=0.7) increased. Similar trend was observed for the heat number. The numerical code developed was validated by opposed to the staggered-grid formulation, and the overall friction-factor, which is representative of parameters, for different Reynolds numbers and for two Periodically fully developed flow and heat transfer in phenomena. High Prandtl number (=7.0) gives higher pressure drop and the heat transfer performance. The pressure. The line-by-line method was used to solve serpentine channel and the Reynolds number were serpentine channels were salved for different geometry SIMPLE algorithm was used to link the velocity and solved for the uniform-wall-heat-flux boundary solving for fully developed flow and heat transfer in symmetry boundary condition. Since this is a forced temperature solver module. The temperature field was the algebraic equations. The geometry of the problem the effect of the independent parameters on the the pressure drop, the local and average Nusselt transfer coefficients. High heat transfer coefficients velocities and pressure, for solving temperature field was established for a reference case of serpentine water respectively). The results were plotted to study were studied. A finite-volume code in FORTRAN was |
