Sloshing Analysis of Rectangular Container with Perforated Baffle
, M.Sc. Thesis Sharif University of Technology ; Dehghani Firouzabadi, Rooholah (Supervisor)
Abstract
In this thesis, sloshing of a rectangular container with perforated baffle is being analysed. Employing the linear sloshing theorem, we construct an accurate numerical and analytical approximation of natural sloshing mode in rectangular container with perforated baffle. Two dimensional irrotational flow of an ideal incompressible liquid is assumed. Finally the dissipated energy is being measured and equal viscous damping was calculated. So the perforation in which the damping is being maximized is determined and finally the results being compared with some experimental and analytical results from journal paper
Electrical and Optical Characterization of Fabricated Carbon-Based Multilayer Structure versus Temperature
, M.Sc. Thesis Sharif University of Technology ; Fardmanesh, Mehdi (Supervisor) ; Zamani, Atieh (Co-Supervisor)
Abstract
This study presents a comprehensive investigation into the characterization of three distinct homogeneous multilayer self-standing thin films, composed of stacked reduced graphene oxide (rGO) planes, which were synthesized using a modified Hummer’s method. In order to investigate their structural, electrical, and optical properties, the samples were characterized by field emission scanning electron microscopy (FESEM), Raman spectroscopy, four-point probe measurements, Impedance measurements, Fourier-transform infrared spectroscopy (FTIR), and Time domain Terahertz Spectroscopy (TDS). The FESEM images obtained from the samples reveal a smooth sheet-like surface with few wrinkles....
