Abstract

A modification to a shell and tube heat exchanger aimed at improving efficiency. The approach involves using nano particles in the fluid and transitioning the fluid flow from laminar to turbulent. Both parallel and counter flows of acting and act upon fluids are considered. The goal is to maintain turbulent flow, as it increases heat exchange efficiency. The swirling effect created by the fluid's turbulence acts as a catalyst, enhancing heat transfer efficiency. The inner tube is made of copper, while the outer tube is transparent Acrylic Plexiglass. The inner tube rotates at speeds ranging from 0 to 1500 rpm. Results show a significant improvement in heat transfer rate due to inner tube rotation. The study involves adjusting factors, measuring and recording data to optimize the heat exchanger's effectiveness and NTU (Number of Transfer Units).
