Computational Modeling of Crack Detection for a Beam using the Finite Element Method

Karmaker, Rajib (CUET, 2024-04-15)

Nowadays the presence of crack in different engineering structures becomes a serious threat to performance. Since most of the civil and mechanical structures may be damaged due to material fatigue, mechanical vibration, ...
The Effect of the Angle of Perforation on Inserts in a Pipe Flow for Heat Transfer Analysis

Acherjee, Simul (CUET, 2024-08-21)

A numerical simulation study of heat transfer analysis is considered with perforated inserts using a different angle of perforation in a circular pipe. In our simulation, we have used 0°, 5°, 10°, 15°, 16°, 17°, 20°, 30°, ...
NONLINEAR ACOUSTIC WAVE PHENOMENA IN MAGNETIZED COLLISIONLESS RELATIVISTIC PLASMAS

Barua, Sagar (CUET, 2024-09-01)

The thesis investigates the nonlinear propagation of ion-acoustic solitons (IASs) within a magnetized rotating relativistic plasma environment. This environment comprises relativistic ion fluids and electrons following ...
Numerical Investigation of Single and Double Differential Cross-Section for the Ionization of Metastable 2S State Hydrogen Atom by Electron Impact

Chowdhury, Md. Thowhidul Hoque (CUET, 2023-12-19)

This thesis focuses on the ionization of hydrogen atoms by electrons in an asymmetric coplanar geometry, which plays a crucial role in atomic ionization problems. The Double Differential Cross Sections (DDCS) from the ...
PROPAGATION OF ION ACOUSTIC SOLITON AROUND THE CRITICAL VALUES OF ANY SPECIFIC PARAMETER IN UNMAGNETIZED COLLISIONLESS RELATIVISTIC PLASMAS

Rahman, Md. Obaidur (CUET, 2024-09-01)

The main purpose of the present work is to investigate how electrostatic plasma parameters modify the nonlinear ion acoustic soliton (IAS) propagation in unmagnetized collisionless plasma including higher order Lorentz ...
Radiation induced structural and electric properties of Al-Substituted NiCuCd nanoparticles

Sharma, Bishakar (CUET, 2024-02-24)

The effect of gamma (γ) irradiations on the physical, magnetic and electrical properties of nanoferrites samples with a chemical formula of Ni0.5Cu0.2Cd0.3Fe2-xAlxO4 have studied. These samples have prepared by sol-gel ...
Similarity solution of unsteady MHD boundary layer flow of a nanofluid for free and forced convection around an inclined plate.

Gani, S. M. Osman (CUET, 2024-06-09)

This study investigates the unsteady magnetohydrodynamic (MHD) boundary layer flow of electrically conducting nanofluids over an inclined plate, considering both forced and free convection. This flow situation is relevant ...
