INTRODUCTION TO MICROCHANNEL

1

“ HISTORY AND DEVELOPEMENT :-

Microchannels were first proposed for electronics coolingapplications by Tuckerman and Pease 1981.

Phillips provided detailedequations 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.

History, Advances, and Challenges in Liquid Flow and Flow Boiling Heat

Transfer in Microchannels A Critical Review by Satish G. Kandlikar

APPLICATION :-◇ Cooling of electronics component

◇ Microchannel heat exchanger

◇ Microchannel reactor

◇ High-performance aircraft gas turbine engines

◇ Heat pumps

◇ Air conditioning

Relatively new topic of disscussion,so their is vast scope of developement.

Miniaturization of electronic component requires more efficient way of optimizing microchannel flows

Unique multiphase flow in microchannels

Microchannel-based MicroFluid devices using electric fields are of recent research interest for various purposes

Field of Interest in Microchannel Flow

Scope of Developement Geometric Optimization of the design of microchannels in heat sinks and heat exchanger.

Establishing a stabilised study on multi phase flow in microchannel.

Further study and developement on the behaviour and effect of flow boiling.

Controlled initiation of turbulent flow in microchannel.

Design and analysis of internally

finned microchannels
