CFD Computational fluid dynamics is widely used in various industrial fields related to fluid, heat transfer and fluid transfer. These include the automotive industry, the aerospace industry, turbochargers, the nuclear industry, the military industry, the oil and gas and energy industries, clean rooms, and many other large-scale industrial applications where the knowledge of computational dynamics has become the solution to related industrial problems. Has been.

These calculations are accompanied by computer simulation. CFDs solve the equations of mass, energy, and motion continuity over a domain specified by the user. This technique is very powerful and covers a wide range of industrial applications. Other advantages of using this method can reduce costs. He mentioned energy consumption in units as one of the main challenges of the industry, maintaining human health, improving the safety of processes, providing solutions for better use of the environment, increasing production capacity and increasing the profit margins of processes.

In complex fluid systems, the use of computational fluid dynamics methods has significantly reduced or even eliminated some laboratory costs. In some cases, given that it is still a good tool for measuring characteristics The desired method is not provided, the computational method is the only possibility to check them.


CFD simulation

Due to the high cost of making physical models of clean rooms before construction and solving the following problems that will occur after construction during the commissioning and use of clean rooms and controlled spaces, accurate simulation software models can be of great help in accurate design. Approve the design as well as simulate conditions and parameters to ensure the design of clean and controlled spaces.

Problems that may arise in the incorrect design of the HVAC system for clean rooms and controlled spaces include:
1- Insufficient air flow distribution
2 - Laminarity or having a smooth flow in some places
3- Not reaching the proper pressure level in clean spaces
4- Creating static currents around the devices and services of a clean room
5- Creating large areas without air flow
6- Improper release of chemical vapors and… from the rooms
7- Very high noise
8- Changes in temperature and humidity in controlled spaces and areas outside the specified limits.

CFD can be used as a powerful tool to eliminate and reduce the above problems in the design of clean spaces and validation (Qualification) and approval of the design of clean rooms. Using computational fluid dynamics methods, such as laboratory methods, requires experience and complete knowledge of different numerical methods and the use of appropriate hardware. In this case, the application of these methods can lead to the simulation of the studied phenomenon.

Andishegaran Jame Sanat Iranian Company, with its specialized, experienced and capable personnel in designing and simulating clean rooms using CFD techniques, has the ability to design and build clean rooms for various industries in accordance with modern world standards. In this company, the design of clean rooms with CFD technology has been simulated and problem points have been solved so that the construction of all spaces of clean rooms is done in accordance with standard conditions and is equal to the valid and qualified requirements.
