This study investigates the dielectric properties and thermal conductivity of boron nitride/polyimide (BN/PI) composites using the Debye relaxation model. Simulations were conducted using MATLAB to analyse the impact of varying BN content on the dielectric constant, dielectric loss, and thermal conductivity across a range of frequencies and temperatures. The... Continue here
Drilling Fluids are critical to oil and gas exploration, with conventional formulations, particularly Oil-Based Mud (OBMs), posing significant environmental challenges due to their toxicity and non-biodegradable nature. This research explores the development and application of biodegradable Drilling Fluids as sustainable alternatives, focusing on current... Continue here
This study investigates steady magnetohydrodynamic (MHD) natural convection Couette flow in a vertical channel, incorporating temperature-dependent fluid properties, namely viscosity and thermal conductivity, to more accurately represent realistic flow behaviour. The analysis accounts for the induced magnetic field by the motion of the conducting fluid, and the... Continue here
This study examines the influence of atmospheric ducting and tropo-scatter on radio wave propagation across five locations in Southern Nigeria: Akure, Abeokuta, Lagos Island, Port Harcourt, and Calabar. Meteorological data from the European Centre for Medium-Range Weather Forecasts (2012-2021) were combined with propagation models to evaluate seasonal and... Continue here
