This document provides an analysis of microchannel heat exchangers. It discusses the history of microchannels dating back to 1981 when they were first proposed for electronics cooling. It also outlines key developments in the field by researchers like Phillips, Colgan, and Kandlikar. Applications of microchannels include cooling electronics, heat exchangers, reactors, engines, and air conditioning. The document discusses the scope for further development in areas like geometric optimization, multiphase flow analysis, and flow boiling control. It provides an overview of the group's project to analyze single phase flow and flow boiling in different microchannel designs using CREO and ANSYS Fluent software.

HISTORY AND DEVELOPEMENT :-
Microchannels were first proposed for electronics cooling
applications by Tuckerman and Pease 1981.
Phillips provided detailed
equations for designing microchannel geometries .
Colgan provided the results of a practical implementation
of enhanced microchannels with a strip-fin geometry.
Kandlikar and Upadhye presented a detailed optimization
procedure for selecting microchannel flow geometries.
