NUMERICAL ANALYSIS OF FLUID FLOW AND HEAT TRANSFER IN MICROCHANNEL
[attachment=65227]
OBJECTIVE
To investigate hydrodynamic & thermal characteristics of micro-channel through Computational Fluid Dynamic modeling & simulation.
Parameter sensitivity study of micro-channel.
Input parameters: (Reynolds‘ Number, Cross-section, Waviness)
Output parameters: (Friction loses, Convective heat transfer coefficient, Temperature)
CONCLUSION
The result of the above graph shows that the heat transfer coefficient increases with the increasing Reynolds’ number.
The heat transfer coefficient greatly increases with the increasing wavy amplitude of the micro-channel.
It can also be observed that the temperature drop in the fluid while its flow through the micro-channel, increases with the increase in the waviness of the micro-channel and the Reynolds’ number.
