the intention of this project is to visualize the airflow inside of a cleanroom ISO4 and the influence of the equipment.                 Die Simulation zeigt ein Segment eines existierenden Reinraums der ISO-Klasse 4 aus den 1980er Jahren. Schon ohne Geraete ist die Luftstroemung weit vom Ideal, senkrechte, turbulenzarme Stroemung, laminar Flow, mit 0,45m pro s, entfernt ist.  Die Luftstroemung mit Equipment zeigt ein weiteres Projekt.

This validation focuses on validating the moment coefficients using experimental results obtained by RWDI in their wind tunnel tests, published in the paper (Calin Dragoiescu, Jason Garber and Suresh Kumar, 2006) where results were published using two techniques, a high-frequency force balance (HFFB) and high-frequency pressure integration (HFPI) which uses tap points. Both showing mostly good agreement between the two, with HFFB expected to be more accurate.

CFD simulation of an HVAC system inside an atrium. Several design version with and without radiators to test radiation capabilities.

To validate CFD results against the Architectural Institute of Japan's Case F results both from the field and wind tunnel,

Behavior of wind crossing through buildings in order to find spots to place a small wind turbine

This project simulates the cooling  of a CAE office building with a server room.

This project demonstrates how to simulate the airflow around a simplified model of a building.

The purpose of this project is to use experimental results from the Architectural Institute of Japan to validate CFD results gained from SimScale. The case being validated is Case E, which consists a complex of buildings with simplified geometry. Many scenarios are presented in Case E, The scenarios used to validate the SimScale platform were the North, East, South and Westerly winds for the after construction scenario.

The SimScale CFD results were compared to the experimental results and found to have good correlation. Some underprediction was seen in the k-epsilon models in the strong wind regions and underprediction in the wake regions, but is a known trait of the K-epsilon model and is acceptable and should be considered when evaluating results.

The purpose of this project is to use experimental results from the Architectural Institute of Japan to validate CFD results gained from SimScale. The case being validated is Case D, which consists of a single high-rise building, surrounded by blocks of simplified buildings. The geometry used was the scaled geometry from the data file provided by the Architectural Institute of Japan, and measurements were taken at points also listed in the data file.

Accurate and reliable computational fluid dynamics (CFD) simulations are essential for the assessment of
cross-ventilation of buildings.
To determine which CFD models are most suitable, validation studies are required.
Therefore, the objective of this simulation is validate a 3D steady RANS simulation of cross-ventilation using OpenFoam (SimScale)
The validation is based on the velocity parameter
The RANS simulation here is conducted with the realizable k-e turbulence models.
The experimentally observed direction of the incoming jet, but all RANS models fail in
It is concluded that choice of the RANS using SimScale Plataform actually produces good results
