Webthe forced convection and buoyancy force are the same, the flow is a buoyancy-aided flow. While, the direction of forced convection and buoyancy force are opposite, the … WebApr 3, 2024 · Case \(\lambda = 0\) corresponds to flow with forced convection, \({\lambda } < 0\) indicates the buoyancy opposed flow and \(\lambda > 0\) presents the buoyancy aided flow. Increase in mixed convection parameter λ can lead to enhance the temperature difference between the surface temperature and the free stream temperature.

WebOct 27, 2024 · Only one syringe pump is needed for the buoyancy-assisted device, and hence the control strategy of the flow rate is simplified as well. Buoyancy-assisted devices were widely studied before the 1990s [31,32,33,34]. Due to the upsurging of soft lithography and other advanced fabrication techniques, devices with more complicated configurations ... Webthe flow condition is classified into laminar and turbulent. In laminar mixed convection, buoyancy-aided flow presents enhanced heat transfer compared to the pure forced convection and buoyancy-opposed flow shows impaired heat transfer as the flow velocity affected by the buoyancy forces. However, in turbulent mixed convection, buoyancy … WebMay 1, 2024 · For the turbulent mixed convection, buoyancy-aided flow impairs heat transfer when buoyancy is low, but enhances it when buoyancy is high. Buoyancyopposed flow always shows enhanced heat transfer ... sign in with a local account
