The solutions of the equations of fluid motion for compressible and incompressible flow in a concentric annular heat pipe have been analyzed. In addition, a similarity solution is presented that can predict the pressure losses in all the segments of the concentric annular heat pipe as well as conventional heat pipes. A theoretical analysis to predict the sonic limit for this new heat pipe is also presented.
