Transport Phenomenon of Simultaneously Developing Flow and Heat Transfer in Twisted Sinusoidal Wavy Microchannel under Pulsating Inlet Flow Condition

نویسندگان

چکیده

Heat transfer operations in microchannel are of special relevance designing micro-devices involving accumulation high heat flux. The current study explores simultaneously developing, unsteady laminar flow inside a twisted sinusoidal wavy and involved. A square cross-sectioned channel is taken for the study. nature as well about axis. modified geometry helps enhancing out plane mixing fluid formation recirculation flow. evaluation performed Reynolds number range 1–100. (varying with time) normal velocity component employed at inlet. was conducted over pulsation amplitude frequency. To solve governing equations, finite volume based method employed. Nusselt data shows significant enhancement inlet compared to that steady case. In terms pressure drop, proposed design different frequencies amplitudes, it can keep drop within admissible limits. Entropy generation used measure dissipated energy. Performance entropy also reported.

Investigation of flow and heat transfer of nanofluid in a diverging sinusoidal channel

Using of nanofluids and ducts with corrugated walls are both supposed to enhance heat transfer, by increasing the heat transfer fluid conductivity and the heat transfer area respectively. Use of a diverging duct with a jet at inlet section may further increase heat transfer by creating recirculation zones inside the duct. In this work two-dimensional incompressible laminar flow of a nanofluid e...
