Fluid movement and heat transmission study of consistent and non-consistent heated porous material has emerged as a discrete study field in the last thirty years, owing to its relevance in abundant applications, including waste used in nuclear power plant and fibres insulations, solar collectors, solar Fresnel and so on. In recent decades, there has been a surge in interest in studying various elements of the porous media. This enormous level of attention has resulted in a slew of research publications addressing a wide variety of issues affecting porous materials, including understanding their structure, deformation, and buoyant heat transfer, to name a few. The investigate of the porous material is one of the classical topics in the field of science. In this research project, free convection is inspected and evaluated on a trapezoidal porous enclosure with analysing dissimilar Rayleigh numbers (10¹ ≤ Ra ≤ 10³) we get efficient results in Rayleigh number 10³, so for our further research on this paper we keep Rayleigh as constant (i.e., Ra = 10³) and aspect ratios (0.25 ≤ H/L ≤ 1). The effect of Ra and AR on temperature contours, Nusselt numbers pf both mean and local has been analysed and presented. This provided a result in which the mean Nu increased by increasing the H/L ratio and Modified Ra. In addition, convection mode is dominant when Rayleigh number is high. The outcome results are differentiated with those found in the literature and were found to be in good accordanc [ABSTRACT FROM AUTHOR] |
