Trial No. 3 to check the Mechanics of the parachute

I want to learn more about the design aspects of the parachute for the Rockets and all. So here it is. Please Chuck it, the speeds are not at all realistic.

This project is more about understanding the mechanics of the Parachutes. So, Let's go, Get it going!

Gathering  Airflow Yield Notwithstanding Obvious User's Elementary Limits

Aerodynamic analysis of a supercar/hypercar. This time I made the vents actually working.
Results at 180 km/h :
Drag : 4345 N, Downforce : 1750 N

Accurate wind pressure coefficients in thermal modelling software (building performance modelling) are critical to evaluating several key design outputs on buildings. The greatest impact of inaccurate wind pressure coefficients will be on the calculation of airflow through openings and thus ventilation, fresh air rates, cooling and overheating assessments can all be adversely affected. Most standard energy/thermal software has an oversimplified treatment of wind pressure which is also poorly understood and applied by software users. 

SimScale can quickly and accurately calculate transient wind flows and pressures around buildings and on building facades. These can be used as in input into energy/thermal software for more accurate building performance modelling.

Aerodynamic analysis of my first car model made on Fusion 360. It comes in a base model and an aerodynamically upgraded version featuring a ducktail and a longer front splitter.

Results : the aerodynamically upgraded version makes around 145 kg of downforce at 180 km/h ( when the regular version makes around 15 kg of lift) but has a 7 percent increase of drag as counterpart.

Flow Analysis Over Alfa Romeo QV without any aerodynamic aids.

Experiments and comparaison of different single seater step planes at 180 km/h (50 m/s). I use a quickly made sort of single seater design.
Results :
Reference (no step plane)              : 1740 N of drag, 330 N of lift.
Flat step plane                                      : 1793 N of drag, 255 N of lift.
Flat step pland and side skirts     : 1800 N of drag, 55N of lift.
Flat step pland and all skirts         : 2025 N of drag, 650 N of lift.
Flat round step plane with skirt : 1880 N of drag, 760 N of downforce.
Angled step plane                               : 1840 N of drag, 450 N of downforce.
Angled step plane with skirts      : 1850 N of drag, 620 N of downforce.

In this simulation, it is aimed to calculate the drag coefficient of an experimental rocket. Although the rocket geometry used is representative, the drag coefficient can be calculated for realistic models by following the simulation steps. K-w SST turbulence model was used for simulation. For the experimental rocket, the speed was taken 270 m / s and a ninety-degree (not realistic) flight angle assumption was made.

The rear wing plays a vital role to maintain the friction on the ground. The simulation analysis a flow over a rear wing developed to study the airflow patterns. An incompressible  external flow analysis is carried out to determine its flow patterns.

Incompressible flow simulation for aerodynamics studies, using SimScale Standard mesh algorighm.

Tutorial project for setting up the mesh using Hex-dominant automatic for external flow.

For a bachelor thesis, the coefficients of drag, lift and pitching moment need to be calculated. Model is a RC Glider.

Engineering study of solar panels, including:

1. Wind loading and static structural analysis of a single panel

2. Transient wind analysis of a panel array

To change with cars I have quickly designed a flying wing drone with a 3m wingspan. At 360 km/h (100 m/s) it makes a surprisingly low drag of 11.94 N and a 1411.5 N of lift.

Examine the flow behaviour on train container body and calculate the drag force for different yaw angle.

Aerodynamic of a track focused car I have made on Fusion 360. Unfortunately an impeachement/bug unables me to make the vents working. At 180 km/h it makes about 3050 N of drag and 230kg of downforce.

Aerodynamic analysis of a speedster track car I designed on Fusion 360 at 180 km/h (50 m/s). It comes in two version :

-A base model making around 2729 N of drag and 2673 N of downforce.
-An RS version including a front splitter and a rear wing, making 3493 N of drag and 4266 N of downforce.

Aerodynamic analysis of a sport car made on Fusion 360. Unfortunately an impeachement/bug unables me to make the vents working.

Following the new 2021 F1 rules, this simulation showcases why is it really important to focus on diminishing the amount of dirty air that the following car is receiving when it comes to wheel-to-wheel battles.

The model was designed by one of my friends who is currently working on a DIY RC plane project. 
He was originally designing a simple glider before revising the design in order to make it a flying boat.

I was asked to analyse the flow around the aeroplane and here it is!
I reckon it still needs more fine tunings (geometry, meshing, sim control, etc.) but I'm chuffed to acheive a decent results.

This project involves meshing externally a platform of some modern design buildings, and then visualizing the behavior of the air that flows through it by simulating it, which is  a common practice nowadays, performed in urban developing, architectural design, environmental planning applications and many more. For the meshing of the maquette configuration of buildings that form this urban landscape, the Hex-dominant parametric (only CFD) and 16 processors were used. A steady state incompressible flow simulation, using the k-omega Spalart Allmaras turbulence model,  is executed, in order to visualize the air flow  as well as the critical areas of the re-circulation. Results from the simulation, as well as flow visualization techniques are also provided from the SimScale and Paraview platforms.

This project involves meshing externally a Boeing 777-200 LR Aircraft, and then simulating its' operation on flight facing an airflow with an axial velocity of 50 m/s.  It is one of the longest-range commercial airliners, with an exterior length and wingspan reaching 63.70 and 64.80 meters respectively.  For this case a model with removed engines was chosen in order to assist convergence and meshing. Also a Symmetry plane was added midst the Part, and half the part was used for meshing and simulation for simplification.  A steady state compressible flow simulation is executed to visualize the air flow around the bodywork and wings of the aircraft, as well as the pressure distribution while on flight.

Project dedicated to understanding the  aerodynamics of a relatively modern road-going hatchback and  ways of improving them.  Self-made model means the results are unlikely to be highly accurate.

The project currently is more about learning about simscale, than immediate results analysis.

Testing the wind interactions with a mobile home.

The goal of this project is to evaluate the aerodynamics of a Boy Scouts of America Pinewood Derby car. This is the first in a series of projects involving many concepts including turbulence modeling, advanced meshing, multiple reference frames, and aerodynamic optimization.  Follow along as we learn more about aerodynamics and how to build an aerodynamic BSA Pinewood Derby winner.
