Numerical simulation is performed to evaluate the privilege of inserting stationary or rotating twisted tape inside a tube as heat transfer enhancement technique. The main emphasis this work placed on understanding effect pitch distance hydrothermal performance such system. obtained results are validated with published experimental findings. numerical study shows that transfer, pressure drop an...

Many components of the storage ring and front ends in the third generation of light sources are subjected to high heat loads from intense x-rays. Temperature rises and thermal stresses in these components must be kept within acceptable limits of critical heat flux and low-cycle fatigue failure. One of the design solutions is to improve heat transfer to the cooling water either by increasing wat...
