| dc.description.abstract | This thesis investigates the heat transfer effects within a semicircular cavity under the influence of a
uniform magnetic field, with a focus on magnetohydrodynamic (MHD) flows. Conducted within the
framework of the Department of Mechanical Engineering at Sonargaon University, Dhaka, Bangladesh,
the study addresses the complex interplay of fluid dynamics, heat transfer, and magnetic field
interactions.
The research begins with the formulation of a comprehensive mathematical model, aligning with the
academic standards of the Department. The model, describing the continuum of continuity, momentum,
and energy equations, is appropriately nondimensionalized to enhance comparability and facilitate a
clear interpretation of dimensionless parameters.
Numerical simulations are performed using the finite element method (FEM), consistent with the
computational practices endorsed by the Department. Special attention is given to mesh generation,
tailored to the computational resources available at Sonargaon University, to ensure high spatial
resolution near the corrugated surface.
Visualization tools such as streamlines and isotherms are employed to effectively communicate fluid
flow patterns and temperature distribution within the semicircular cavity, adhering to visualization
standards set by the Department.
A comprehensive parametric study is conducted, varying Rayleigh number, and heating ratio, in line
with numerical simulation practices. The analysis focuses on the effects of these parameters on
streamlines, isotherms, velocities, and Nusselt number.
Results indicate that an increase in the Rayleigh number and heating ratio correlates with heightened
heat transfer rates.
Validation against existing models is performed following the Department's standards for verification
