The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.

Hot-wire experimental investigation on turbulent Prandtl number in a rotating non-isothermal turbulent boundary layer

Propulsion and Power Research, 2020
This experiment used a parallel array of hot wire probes to simultaneously measure the temperature and velocity fields in the non-isothermal turbulent boundary layer of a rotating straight channel. The Reynolds numbers are 15,000 and 25,000, respectively.

Scale dependence of the marine atmospheric boundary‐layer response to ocean surface‐temperature variability in the EUREC4$$ {\mathrm{EUREC}}^4 $$A region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
With a minimal physics model and a high‐resolution fully 3D simulation, we demonstrate that the marine atmospheric boundary layer (MABL) response to sea‐surface temperature (SST) variability displays a dependence on the horizontal scales of motion.

Finite Difference Analysis of Prandtl Number and Particle Volume Fraction Effects on Skin Friction and Heat Transfer in Buoyancy Driven Two-Phase Flow with Suspended Particulate Matter (SPM)

East European Journal of Physics
A numerical investigation has been conducted on incompressible, laminar two-phase buoyancy driven flow containing suspended particles around a vertical plate. Despite the relevance of such systems, prior studies have largely overlooked natural convection

Theoretical Assessment of the Sodium Pool Fire's Burning Rate in an Open Environment

Safety Science and Technology, EarlyView.
An evaporation‐based model is developed for sodium pool fires. Experiments demonstrate that the burning rate increases with pool diameter and approaches a quasi‐saturated limit (∼0.013 kg m−2 s−1) governed by oxidation product conversion. ABSTRACT The burning rate of sodium pool fires is a critical parameter for assessing fire development and ...
