Miniaturization of electronic components requires compact and effective cooling techniques to dissipate large heat flux without a significant increase in pumping power. With content from Ansys experts, partners and customers you will learn about product development advances, thought leadership and trends and tips to better use Ansys tools. . ieee. Introduction. [ 21 ] investigated the shape optimization of wavy mini-channel heat sink by multi-objective optimization algorithm. 2016: Numerical: Tapered channels: water • High convergence angle increases thermal performance. The adopted computational approach is based on a finite-volume formulation of the lattice Boltzmann method constructed on a fully-unstructured mesh. . Download the WAVY Weather app for fast, accurate local and national weather at your fingertips.
A fixed temperature and velocity are considered at the inlets of the inner and outer tubes for the fluid flow and the outlet is considered as an outflow.

Laminar forced convection of heat transfer and pressure drop of Al 2 O 3 and CuO/water nanofluids flow through a horizontal tube and wavy channel under constant wall temperature boundary condition. The effect of viscous dissipation on heat transfer through nano-fluid in a vertical wavy channel filled with porous media has been studied.

The consequential differential equations are simplified. Wavy channels were investigated in this paper as a passive scheme to improve the heat transfer performance of laminar fluid flow as applied to microchannel heat sinks. Different corrugations considered are wavy. . . . 1, αw = 0. This confirms that µ also linearly scales up with the number of fins. The fluids are water, a nanofluid of 1% TiO2 in a water solution and a hybrid fluid which consists of 1% Al2O3–Cu nanoparticles in a water solution.

Helium is used as a working fluid and alloy 617 as solid substrate. . A lot of work has been done in the fully rough regime at high Reynolds numbers where the effect on the outer layer turbulence structure and the resulting friction drag is well documented. Findings. See http://www. The structure of turbulent flow over non-flat surfaces is a topic of major interest in practical applications in both engineering and geophysical settings. .
