| Abstract: | Three-dimensional numerical simulation was performed for the laminar fluid flow and heat transfer in the shell side of an experimentally tested shell-and-tube heat exchangers with helical baffles on the basis of porous medium and distributed resistance assumptions.The numerical results coincide with the test data satisfactorily,indicating that the analytical model is feasible for simulating the flow and heat transfer characteristics of the helically baffled shell-and-tube heat exchangers. |
