Numerical simulation of silicon micro flat heat pipes with axial triangle grooves

One-dimensional model is developed and solved numerically to investigate the flow of liquid and vapor in triangle grooves. The effect of liquid and vapor interfacial shear stress is taken into account in this model that can greatly improve the accuracy of the results. The results obtained from this simulation contain behaviors of pressure and flow patterns, the effect of different working conditions and so forth. In addition, maximum heat transport capacity of micro heat pipe is calculated. The model predicted results are successfully compared with the experimental results from the published results in literature. The general nature of the model and the associated parametric study ensure the wide applicability of the model.
