Dimensional optimization of silicon microchannel heat sinks is performed by minimizing the total thermal resistance. Intel Core i7-900 Desktop Processor of chip core dimensions of 1.891 cm x 1.44 cm is considered as a reference processor which is reported to dissipate 130 W of heat. The properties are evaluated at the area weighted average of the fluid inlet and iteratively calculated outlet temperatures. The effects of the thermal and hydrodynamic entrance regions on heat transfer and flow are also investigated. The results of the optimization code agreed very well with available ones in the literature.

Dimensional optimization of microchannel heat sinks with multiple heat sources Turkakar, Goker; Okutucu Özyurt, Hanife Tuba (2012-12-01) Dimensional optimization of silicon microchannel heat sinks is performed by minimizing the total thermal resistance. Intel Core i7-900 Desktop Processor of chip core dimensions of 1.891 cm x 1.44 cm is considered as a reference processor which is reported to dissipate 130 W of heat.

Gradient-based optimization of micro-scale pressurized volumetric receiver geometry and flow rate Akba, Tufan; Baker, Derek Keıth; Mengüç, M. Pınar (2023-02-01) This study focuses on the design optimization of a micro-scale pressurized volumetric receiver by changing geometry and flow rate constrained by the volume, outlet air temperature, and outer surface temperature. The pressurized volumetric receiver model is replicated from an existing model, which assumes constant air pressure and neglects the convection loss from the cavity. The existing model is revised from a solver to a design optimizer. The replicated model is restructured using OpenMDAO (Open-source Mu...
Enhanced thermal conductivity of nanofluids: a state-of-the-art review Özerinç, Sezer; Yazicioglu, Almila Guevenc (2010-02-01) Adding small particles into a fluid in cooling and heating processes is one of the methods to increase the rate of heat transfer by convection between the fluid and the surface. In the past decade, a new class Of fluids called nanofluids, in which particles of size 1-100 nm with high thermal conductivity are Suspended in a conventional heat transfer base fluid, have been developed. It has been shown that nanofluids containing a small amount of metallic or nonmetallic particles, Such as Al2O3, CuO, Cu, SiO2,...
EFFECT OF SURFACE ROUGHNESS IN PARALLEL-PLATE MICROCHANNELS ON HEAT TRANSFER Turgay, M. B.; Güvenç Yazıcıoğlu, Almıla (Informa UK Limited, 2009-01-01) In this study, the effect of surface roughness on convective heat transfer in two-dimensional parallel plate microchannels is analyzed numerically for steady-state, single-phase, developing, and laminar air flow in the slip flow regime. Slip velocity and temperature jump at wall boundaries are imposed to observe the rarefaction effect. The effect of triangular roughness elements on Nusselt number are compared to cases with smooth surfaces. The results indicate that increasing surface roughness reduces heat ...
Analysis of stress in a solid cylinder with periodic heat generation Varlı, Ekin; Eraslan, Ahmet Nedim; Department of Engineering Sciences (2015) Thermoelastic stress response of a periodic heat generating solid cylinder is investigated by analytical means. The cylinder is initially at zero temperature. For times greater than zero, heat is generated internally and slowly at a time dependent rate. Two periodic heat generation rates are used. The temperature distribution in the solid cylinder corresponding to each generation rate is obtained by making use of Duhamel’s theorem. An uncoupled thermoelastic solution of the solid cylinder is then obtained u...
