Article Synopsis
  • A cylindrical shell is a structure with a curved surface around a central axis, commonly used in applications like pressure vessels, heat exchangers, and aerospace.
  • The article examines four layers of materials, focusing on functionally graded and isotropic materials, and derives the natural frequency through the Rayleigh-Ritz approach based on Sander's shell theory.
  • MATLAB software is utilized to compute natural frequencies for various thickness-to-radius and length-to-radius ratios under simply supported edge conditions.

The purpose of this work is to probe the analytical formulation of the mechanical response [Formula: see text], which is the consequence of determining the connection between charge and depth values. It is possible to acquire the [Formula: see text] expression by doing an indentation experiment while the loading process is unfolding. In this particular piece of research, the formulation of [Formula: see text] takes into consideration the pile-up mode for an indenter with a spherical structure.

This study presents a sophisticated numerical simulation model for a forced circulation solar water heating system (FC-SWHs), specifically designed for the unique climatic conditions of Algeria. The model aims to cater to the hot water needs of single-family houses, with a daily consumption of 246 L. Utilizing a dynamic approach based on TRNSYS modeling, the system's performance in Ain Temouchent's climate was scrutinized.

Vortices capture the attention of every scientist (as soon as they come into existence) while studying any flow problem because of their significance in comprehending fluid mixing and mass transport processes. A vortex is indeed a physical phenomenon that happens when a liquid or a gas flow in a circular motion. They are generated due to the velocity difference and may be seen in hurricanes, air moving across the plane wing, tornadoes, etc.

Article Synopsis
  • The study explores natural convective heat transfer in a square porous cavity with a composite wall filled with a hybrid nanofluid (35% MWCNT-65% FeO) in water, highlighting the effects of heat distribution and porous material properties.
  • Using the Darcy-Brinkman-Forchheimer model along with COMSOL software, various dimensionless parameters like modified Rayleigh number, Darcy number, and wall amplitude are analyzed to understand their impacts on heat transfer performance.
  • Results indicate that heat transfer efficiency is highest at certain parameters (Ra*=10, Da=10, and solid volume fraction φ=0.05), with conduction dominating at high Darcy numbers, while convection becomes more significant as Darcy numbers decrease and wall
