Elliptical pillars for the thermal performance enhancement of micro-structured evaporators Yuncu, Goksel; Akkus, Yigit; Dursunkaya, Zafer (2023-11-01) In this study, we propose and investigate the employment of elliptical micropillars as a novel evaporator wick structure to boost the performance of capillarity-driven two-phase heat spreaders through high-fidelity numeric...
Comprehensive three-dimensional hydrodynamic and thermal modeling of steady-state operation of a flat grooved heat pipe Gökçe, Gökay; Kurt, Cem; Odabaşı, Gülnihal; Dursunkaya, Zafer; Çetin, Barbaros (2023-03-01) Mathematical modeling of grooved heat pipes is a challenging task since multiple coupled physical phenomena such as phase change, free-surface flow and heat transfer are involved. Moreover, the fact that the shape of the l...
Interplay of capillary and Marangoni flows in micropillar evaporation Yuncu, Goksel; Akkus, Yigit; Dursunkaya, Zafer (2023-2-01) The evaporation from a micropillar evaporator is a problem governed by various interfacial phenomena such as the capillarity-induced liquid flow, thin-film evaporation intensifying near the contact lines, and thermocapilla...
Elliptic Micropillar Wick Evaporators for Thermal Management of High Flux Electronics Yuncu, Goksel; Akkus, Yigit; Dursunkaya, Zafer (2023-01-01) Advances in chip manufacturing technologies and ascending transistor numbers led to a drastic increase in the thermal loads of electronic components. Since increasing tem-peratures limits the performance and lifespan of el...
EFFECT OF LIQUID-VAPOR INTERACTION ON THE THERMAL PERFORMANCE OF A FLAT GROOVED HEAT PIPE Derebaşı, Beste; Saygan, Samet; Çetin, Barbaros; Dursunkaya, Zafer (2023-01-01) Flat grooved heat pipes (FGHP) are predominantly used in electronics cooling due to their ability to transfer high heat loads with small temperature differences and superior reliability. Modeling the underlying physics is ...
Capillary boosting for enhanced heat pipe performance through bifurcation of grooves: Numerical assessment and experimental validation Saygan, Samet; Akkus, Yigit; Dursunkaya, Zafer; Cetin, Barbaros (2022-10-01) © 2022 Elsevier LtdIn this study, an enhanced heat pipe performance for grooved heat pipes has been demonstrated through capillary boosting with the introduction of the bifurcation of grooves. Wider grooves regularly branc...
Fast and predictive heat pipe design and analysis toolbox: h-pat Saygan, Samet; Akkuş, Yigit; Dursunkaya, Zafer; Çetin, Barbaros (2022-01-01) For the assessment of the thermal performance of heat pipes, a wide range of modeling is available in the literature, ranging from simple capillary limit analyses to comprehensive 3D models. While simplistic models may res...
