Prediction of Energy Concentration during Microwave Heating with a Thermal Diffusion Dimensionless Number

Journal of Chemical Engineering of Japan
In a previous study, the correlation equation with a dimensionless number (As) of local microwave heating was proposed to solve the problem of a wider temperature distribution caused by heat generation within penetration depth during microwave heating ...

Effect of Slip Conditions and Entropy Generation Analysis with an Effective Prandtl Number Model on a Nanofluid Flow through a Stretching Sheet

Entropy, 2017
This article describes the impact of slip conditions on nanofluid flow through a stretching sheet. Nanofluids are very helpful to enhance the convective heat transfer in a boundary layer flow.

Development of New Turbulent Prandtl Number Models for Low- and Medium-Prandtl-Number Fluids via Multi-Gene Gene Expression Programming

Applied Sciences
The study of turbulent Prandtl number is important for turbulent flows with heat transfer. Despite its importance, no universal model exists that is able to capture its behavior for a range of molecular Prandtl numbers.

Prandtl Number Effects on Mixed Convection Between Rotating Coaxial Disks

International Journal of Rotating Machinery, 1996
Prandtl number characterizes the competition of viscous and thermal diffusion effects and, therefore, is an influential factor in thermal-fluid flows. In the present study, the Prandtl number effects on non-isothermal flow and heat transfer between two ...

Radiative Hybrid Nanofluid Flow Over a Porous Riga Surface: A Fuzzy–ANN Modeling Approach

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a fuzzy–ANN model to investigate the nonlinear thermal transport in a tangent hyperbolic (Tanh) hybrid nanofluid flow past a porous Riga surface, considering the effects of Rosseland diffusion, chemical reactions, and internal volumetric heating.

Scale of plume clustering in large-Prandtl-number convection [PDF]

, 2021
Clustering of plumes in turbulent Rayleigh-Bénard convection has been numerically observed in low-Prandtl-number fluids. In this framework, turbulent plumes undergo a phase-separation process leading to large-scale clusters and circulations, sometimes ...
