Abstract:

A heat exchanger is a device in which heat is transferred from a high-temperature fluid to a low-temperature fluid. Where the heat exchange that occurs in two types of different temperatures are not in contact, namely the heat transfer fields which are generally in the form of pipe walls or fins mounted on the pipe (fin) so that the two fluids will reach the same final temperature in the amount of heat. The displacement is estimated by equating the losses from the hotter fluid energy with obtaining a lower fluid energy, which is used for heat exchange in the form of the product itself, namely:

The main objective of our work is to analysis the heat transfer rate for various fluids with different matrix heat exchanger (MHE) models and flow characteristic in matrix heat exchanger by using computational fluid dynamics (CFD) package with small car. The amount of heat carried by the cold fluid from hot fluid is mainly depends upon the mass flow rate of the working fluid. The heat transfer area per unit volume of tube is more. So, it increases the temperature of the cold fluid. Here, the hot and cold fluids are moving in the alternate tubes of heat exchanger in the counter flow direction.

The prime motive of this experimental study is to design a helical coil and shell heat exchanger and analyzing thermal performance based on convection heat transfer. Then, a polysaccharide, guar gum is used to lessen the drag force of cold water in helical pipe inside the heat exchanger, which ultimately lowers the amount of pumping power needed. The shell is made by rolling a square sheet and tube is formed by bending of straight pipe. Then, they are joined by spot welding to fabricate the complete heat exchanger.

Active control of radiation heat transfer in liquids can be accomplished with the use of a class of fluids referred to here as electro-controllable (EC) fluids. EC fluids in general consist of a colloidal suspension of polarizable, micron-size particles dispersed in a carrier fluid with an appropriate dielectric constant. When an electric field is applied, the particles redistribute in the fluid, changing from a uniformly dispersed configuration to a tightly organized chain formation that follows the lines of the electric field, thus causing a change in the thermal radiation transport.

Differently, for the Na and K as working fluid, the heat flux raised quickly but declined slower. Therefore, the alka
