The minimum meniscus radius occurring in the heat pipe determines the maximum capillary heat transport. The accurate prediction of minimum meniscus radii plays a key role in designing a highly efficient heat pipe cooling device. In the current investigation, a mathematical model predicting the minimum meniscus radius occurring in the sintered particles is developed. If the particle size distribution is given, the model can be used to predict the minimum meniscus radii in sintered particles.
