The steady incompressible flow has been solved in cylindrical coordinates in both vapour region and wick structure. The governing equations in vapour region are continuity, Navier-Stokes and energy equations. These equations have been solved using SIMPLE algorithm. For study of parameters variation on heat pipe operation, a benchmark has been chosen and the effect of changing one parameter has been analyzed when the others have been fixed.<\/p>\r\n","references":"[1] Amir Faghri, Heat Pipe Science and Technology, Taylor & Francis\r\nPublishing, 1995.\r\n[2] A.
