WebThe application of turbulent heat transfer to internal geometry (corrugated pipe or channel) can be found in a wide range of engineering systems, such as combustion chambers, heat exchangers, nuclear reactors, and so on, where the turbulence in the fluid acts to enhance the mixing of thermo-fluid system. WebThe thermal performance of heat exchangers is very dependent on the physical properties of the two fluids passing through them. It’s also dependent on the “dynamic condition” of those fluids. The latter refers to the flow direction, velocity and degree of turbulence present in the fluids exchanging heat. LAMINAR vs. TURBULENT FLOW Figure 4-1
