Tunnel Ventilation Performance Under Fire: CFD Analysis & Safety Insights
A performance study focusing on a tunnel ventilation system under both normal operation and emergency fire conditions. The aim was to analyze the interaction between jet fans, tunnel geometry, and air/smoke behavior in critical scenarios.
CFD of a Venturi Air Conditioner Unit
A CFD was performed to simulate the concept of the device. Then another CFD was done to simulate the device’s effect on a certain room. The design concept relies on refreshing the air more than other air conditioners in the Egyptian market. This is achieved by the Venturi effect.
Cooling a bottle of liquid using a Peltier module
The purpose was to simulate which Peltier TEC is effective in cooling down a liquid inside a bottle. This was achieved through an aluminum base with a certain decrease in temperature degrees in a certain time.
The simulation was part of designing a unique cooling wine base.
CFD of Horizontal Axis Wind Turbine (HAWT) Blade
This assessment aims to conduct a 2D CFD analysis on a HAWT blade airfoil using ANSYS Fluent. It will compare the numerical results with experimental data. The analysis calculates lift, drag, and moment forces for the ‘NACA 63(4)-221’ blade profile. It does this across a range of angles of attack.
EPS vs. Rockwool: Which Fire-Rated Wall Performs Better?
Comparison between two fire-rated wall configurations, focusing on thermal insulation, fire safety, and compliance with international fire standards. The goal was to identify which setup offers the best balance between energy efficiency and fire protection.
CFD for several solar panel structures.
A CFD simulation evaluated various solar panel designs. These designs were at different angles and elevations. They were exposed to a wind speed of 128 mph. It revealed drag results for the lower face of the panels. It compared the drag across different areas within the same design. It also compared the drag among different designs.
CFD for several solar panel structures.
A CFD thermal analysis shows the cooling process. It demonstrates how the hot water of the petrol engine cools through the pipes of the radiator.
CFD of an Electric Cigarette (Vape)
The CFD was a stage of the design for a Vape, for testing the performance of two designs.
The simulations demonstrated how the two designs would function. They also showed how air, from breathing, and vegetable oil would mix and reach the user.
CFD and FEA of a Gorlov turbine
A CFD simulation was performed on a Gorlov turbine “vertical wind Turbine” blades at a certain angular speed. The goal was to obtain contours of pressure on the blades. Then these data were used to obtain the structural data. They determined stress, strains, and deformation caused by the pressure on the blades.
Structural Analysis of Trestle Stand
We assumed a load of 2 tons was pressing on the middle of the C-beam
Results show that: The maximum deformation of 0.18 mm in the middle of the C-beam. The maximum stress applied is about 7*10^7 which is too small a value for the static yield strength of steel.
Design a Water Bucket for a firefighting Helicopter
We redesigned the structure of Water Bucket to increase its capacity. We applied FEA to ensure that our design is safe. The design includes choosing the same component sources. Lightweighting was done to reduce the weight of the whole system. After that, the shop drawings were exported for manufacturing.
