Numerical Investigation of Eel Movement
, M.Sc. Thesis Sharif University of Technology ; Abbaspour, Majid (Supervisor)
Abstract
In this work, we use computational fluid dynamic simulation tools for investigation two dimensional of eel movement. Firstly, the numerical study of smooth particle hydrodynamics was applied for determination drag coefficient and lift coefficient of undulation movement eel body. The initial mesh was manual. So, the effective parameters of eel movement were investigated. The smooth particle hydrodynamic method was not use, because of saving on time. Therefore, fluent software was used. UDF were added to the fluent software, which it can be move the boundary layer of mesh with eel movement. The dynamic mesh tools of fluent software were used. Initial shape had a curvature and utilized for...
Optimizing the Aquaculture Net Washer's Washing System
, M.Sc. Thesis Sharif University of Technology ; Khorasanchi, Mahdi (Supervisor) ; Mehdigholi, Hamid (Supervisor)
Abstract
In this project, experimental investigation and optimal design of the aquaculture netwasher process for biofouling removal have been studied. In the first phase, various types of marine biological deposits and their characteristics were examined, and the most prevalent type with the highest adhesion was selected for the net. In the second phase, different cleaning methods were evaluated, and the most efficient method considering cost, equipment, and speed was chosen. Following an assessment of the challenges, advantages, and disadvantages of the mentioned methods, a rotational disk system was selected as the preferred system due to its cost-effectiveness, cleaning speed, reduced damage to...
