Investigation of Laminar Pulsating Nanofluid Flow and Heat Transfer in a Rectangular Channel
In this study, two-dimensional pulsating unsteady flow of nanofluid through a rectangular channel with isothermal walls is investigated numerically. The set of resultant algebraic equations is solved simultaneously using SIMPLE algorithm to obtain the velocity and pressure distribution within the channel. The effects of several parameters, such as volume fraction of different nanoparticles, Rey...
متن کاملNumerical investigation of heat transfer in a sintered porous fin in a channel flow with the aim of material determination
Extended surfaces are one of the most important approaches to increase the heat transfer rate. According to the Fourier law, the heat transfer increases by increasing the contact surface of body and fluid. In this study, the effect of heat transfer has been investigated on two sets of engineered porous fins, in which the balls with different materials are sintered together. The fluid flow throu...

متن کاملNumerical Investigation of Heat Transfer and Pressure Drop in a Corrugated Channel
The influence of variation in rib-height to channel-height ratio (e/H) on the heat transfer and pressure drop characteristics inside a channel with corrugated upper and lower plates was investigated numerically in the present study. The governing equations were solved by using finite volume approximations for a wide range of (0.06 < e/H < 0.26) and Reynolds numbers (5400 < Re < 23000), with a m...
متن کاملImproving the natural convective heat transfer of a rectangular heatsink using superhydrophobic walls: A numerical approach
The effect of utilizing superhydrophobic walls on improving the convective heat transfer in a rectangular heatsink has been studied numerically in this paper. The vertical walls were kept at isothermal hot-and-cold temperatures and horizontal walls were insulated. The boundary condition on the walls was: no-slip for regular, and slip (with slip length of 500 µm) for superhydrophobic walls. By c...
