Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The objective of the current research is to characterize the thermal performance in micropolar fluid flows on a vertically elongated porous sheet in the presence of buoyancy forces. Thus, the motivation of this study is to improve the understanding of buoyancy‐driven micropolar fluid flows through porous media, which are relevant to advanced ...

Simulation of copper-water nanofluid in a microchannel in slip flow regime using the lattice Boltzmann method with heat flux boundary condition [PDF]
, 2015 Laminar forced convection heat transfer of water–Cu nanofluids in a microchannel is studied using the double population Thermal Lattice Boltzmann method (TLBM). The entering flow is at a lower temperature compared to the microchannel walls.

Upper bounds on Nusselt number at finite Prandtl number
Journal of Differential Equations, 2016 We study Rayleigh B nard convection based on the Boussinesq approximation. We are interested in upper bounds on the Nusselt number $\mathrm{Nu}$, the upwards heat transport, in terms of the Rayleigh number $\mathrm{Ra}$, that characterizes the relative strength of the driving mechanism and the Prandtl number $\mathrm{Pr}$, that characterizes the ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The hybrid nanofluid integrated with micropolar fluid shows growing interest due to the enhanced thermal performance in microscale devices. These improved properties are due to their greater thermal conductivity and rotational effects. The proposed study assesses the significance of velocity slip on the flow characteristic of micropolar ...

Cold Zone Exploration Using Position of Maximum Nusselt Number for Inclined Air Jet Cooling
Archive of Mechanical Engineering, 2017 Inclined jet air cooling can be effectively used for cooling of electronics or other such applications. The non-confined air jet is impinged and experimentally investigated on the hot target surface to be cooled, which is placed horizontally.

Resolving the fine-scale structure in turbulent Rayleigh-Benard convection [PDF]
, 2013 We present high-resolution direct numerical simulation studies of turbulent Rayleigh-Benard convection in a closed cylindrical cell with an aspect ratio of one. The focus of our analysis is on the finest scales of convective turbulence, in particular the

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The utilisation of viscoelastic Walter's B nanoliquid in engineering and biomedical applications gained substantial attention because of its ability to provide real‐time fluid behaviour, particularly in the heat flow mechanism. In particular, the flow of viscoelastic fluid over an elongating surface is useful in polymer processing and ...
