“…Configuration of streamlines exiting the side grills of air coolers showed the necessity to address the issue of the special air distributor -deflector which will even the air flow and direct it uniformly towards the periphery of the side rows of pallets. This is in conformity with the results presented in [9].The temperature distribution along the line passing through the center of the row of cages adjacent to the axial line at different heights is presented in Fig 2 and 3.…”

The developed 3-D model of the blast freezer showed its adequacy of simulated processes to those observed in practice. It has shown its versatility and high flexibility as per the range of the variable data which can be changed in the process of simulation, and thus whose influence can be studied. The model allow to determine the optimum positioning of pallets including the distance between them in files and rows providing the highest efficiency of the process, as per the cycle duration and compact loading of freezer per cycle. The model can be used at a stage of freezer and air distribution designing calculations.

“…A diffuser with a half cone angle of 70 was found to provide maximum static pressure recovery and exhibit better performance. Uraijaree et al 22) studied the effects of designs of ceiling diffusers with various concentric circles on airflow patterns using computational fluid dynamics simulations software. It was found that a ceiling diffuser with five concentric circles improves airflow quality at the outlet by 13.57% which reduced shortened freezing time.…”

HVAC (heating ventilation and air conditioning) deals with cooling and heating buildings and providing clean conditioned air for indoor environments such as commercial office spaces, cinemas, and hotels to name a few. Diffusers help to effectively distribute air coming from HVAC ducts into indoor environments. Understanding the flow distribution from the diffuser is of great significance as it helps in locating the optimal location for the diffuser as well helps in designing a better diffuser. With the advent of high-performance computing, numerical simulation is mainly being used to predict airflow via Computational fluid dynamics (CFD). OpenFOAM is an open-source CFD solver written in C++ for solving fluid dynamics problems. In this work, a free architecture design tool called PCON was used to create the geometry of the office/home along with the furniture. OpenFOAM was used to create a mesh and simulate the flow through a square ceiling diffuser and understand the Coanda effect which is created by such a diffuser. Open source code called Paraview was used to analyze the CFD simulations and the results were reported in this paper. In central A/C systems, Freon has been used for decades. Freon, just like R12, has been linked to environmental damage. This work shows how diffusers can help with the efficient distribution of conditioned air in closed spaces. With the efficient distribution of air, Freon would be used less and in turn, more efficiently in a given space. This could prevent environmental damage to some extent.
