The Evolution of Turbulent Micro-vortices and their Effect on Convection Heat Transfer in Porous Media [PDF]
, 2021 New insight into the contribution of the microscale vortex evolution towards convection heat transfer in porous media is presented in this paper. The objective is to determine how the microscale vortices influence convection heat transfer in turbulent flow inside porous media. The microscale temperature distribution is analyzed using flow visualization

On high Taylor number Taylor vortices [PDF]
, 2022 Axisymmetric steady solutions of Taylor-Couette flow at high Taylor numbers are studied numerically and theoretically. As the axial period of the solution shortens from about one gap length, the Nusselt number goes through two peaks before returning to laminar flow.

Thermal flux in unsteady Rayleigh-Bénard magnetoconvection [PDF]
International Journal of Heat and Mass Transfer 142 (2019) 118413, 2019 We present results of numerical investigation on thermal flux in Rayleigh-B\'{e}nard magnetoconvection in the presence of a uniform vertical magnetic field. We have studied thermal flux in different viscous fluids with a range of Prandtl number ($0.1 \le \mathrm{Pr} < 6.5$) and a range of Chandrasekhar number ($50 \le \mathrm{Q} \le 2.5 \times 10^4 ...

Comprehensive study of forced convection over a heated elliptical cylinder with varying angle of incidences to uniform free stream [PDF]
Volume 194, December 2023, 108588, 2023 In this paper we carry out a numerical investigation of forced convection heat transfer from a heated elliptical cylinder in a uniform free stream with angle of inclination $\theta^{\circ}$. Numerical simulations were carried out for $10 \leq Re \leq 120$, $0^{\circ} \leq \theta \leq 180^{\circ}$, and $Pr = 0.71$.
