Heat pipes, which use the phase change heat transfer mechanism, are widely used in various terrestrial , aviation and space applications due to their capability of carrying large amounts of heat with a small temperature difference. The working loop of a heat pipe includes condensation, capillary flow of the condensate, evaporation and cross flow of the vapor. Accurate modeling of each of these phenomena is crucial to estimate the overall performance of a heat pipe. The condensation phenomenon is the least studied in literature and current models suffer from the lack of accuracy in estimating the liquid-vapor interface profile on the fin top. Focusing on the modeling of condensation in rectangular grooved heat pipes, the present study develops a new approach to model the capillary induced free surface flow in the neighborhood of a corner region, which in a heat pipe, is the intersection of the fin top and the groove wall. The liquid film profile obtained for constant mass flow rate and for a representative condensation model are presented.

A new approach to thin film evaporation modeling Akkuş, Yigit; Dursunkaya, Zafer (2016-10-01) Heat pipes which use phase change heat transfer mechanism and can carry large amounts of heat, are preferred in the cooling of high heat dissipating electronic components due to the fact that they are self-operating devices with ease of manufacturing for different geometries and ability of performance in micro-gravity applications. Heat pipes having rectangular micro channels as wick structure are used in many studies because of the relative ease of developing analytical and numerical solutions to problems ...
A CSCM Approximation of Steady MHD Flow and Heat Transfer Between Parallel Plates with Hydrodynamic Slip and Convective Boundary Conditions Tezer, Münevver; Türk, Önder (2021-01-01) © 2021, Springer Nature Switzerland AG.The steady magnetohydrodynamic (MHD) flow and heat transfer between parallel plates is considered in which the electrically conducting fluid has temperature dependent properties such as viscosity, thermal and electrical conductivity. The fluid is driven by a constant pressure gradient, and a uniform external transverse magnetic field is applied perpendicular to the plates. The effects of viscous and Joule dissipations are considered in the energy equation, and the flui...
An Experimental and numerical investigation of warpage behavior of silicon substrates at cryogenic temperatures Baloğlu, Eyüp Can; Okutucu Özyurt, Hanife Tuba; Dursunkaya, Zafer; Department of Mechanical Engineering (2016) Surface deformations and thermal stress behavior of microelectronic devices that operate at cryogenic temperatures (less than 120 K) and under vacuum conditions are important phenomena that aff ect the reliability requirements of such components. Excessive deformation and thermal stress on these devices may result in interconnect failure, performance degradation or other direct mechanical failure of one or more components. To obtain reliable products, surface deformations, named as warpage most widely, and ...
A novel approach to condensation modeling at the fin top of a grooved heat pipe Akdağ, Osman; Dursunkaya, Zafer; Department of Mechanical Engineering (2019) Phase-change passive heat spreaders have the capability of carrying large amounts of heat from a heat source to a heat sink creating a small temperature difference. One common type of the passive heat spreaders is the heat pipes. The liquid flow inside a heat pipe is driven by the capillary pressure gradient created by a wick structure on the inner wall, which may be in the form of grooves, sintered grains or wire meshes. In the literature, grooved heat pipes are the most studied ones for modeling and exper...
A CSCM approximation of steady MHD flow and heat transfer between parallel plates with hydrodynamic slip and convective boundary conditions Tezer, Münevver; Türk, Önder (null; 2019-10-04) The steady magnetohydrodynamic (MHD) flow together with its heat transfer between parallel plates is considered in which the electrically conducting fluid has temperature dependent properties such as viscosity, thermal and electrical conductivity. The fluid is driven by a constant pressure gradient, and a uniform external transverse magnetic field is applied perpendicular to the plates. The effects of viscous and Joule dissipations are considered in the energy equation, and the fluid is assumed to be slippi...
