Paper Title
numerical study on optimization of heat transfer through a micro channel
Authors

Abstract
the presented study deals with slug flow in a micro channel with wall heat flux boundary condition. A cfd analysis has been carried out on a 2-dimensional axisymmetric model with three different heat flux value and nusselt no. is plotted. Also the taylor bubble formed is analyzed by plotting the air volume fraction to represent the bubble. The three heat flux values are 10000 W/m2, 20000 W/m2 and 30000 W/m2 which corresponds to the average nusselt number 17.255, 17.377 and 16.493 respectively which shows that at first nusselt number increases by increasing the heat flux at wall and then it decreases and hence maximum heat transfer occurs at 20000 W/m2 heat flux. The local wall temperature along the length and local nusselt number along the wall is also plotted in analysis. The results obtained in the study is validated against the existing work and found in good agreement with the existing data

Keywords- computational fluid dynamics, micro channel, local nusselt number, air volume fraction, slug flow, heat flux
