Air Flow Analysis for Electrical Motor's Cooling System With Autodesk Simulation CFD 2013 Program

Abstract

In the article the analysis of airflow through electrical motor was conducted and optimal design solution was chosen in order to increase cooling efficiency. Numerical simulations allow to determine the areas of temperature occurrence which may have destructive influence on electrical motor parts and on its safe operation. The numerical calculations of airflow was carried out for two different types of fans as well as for two different housings. An analysis of the construction was carried out by CFD method using Autodesk Simulation CFD 2013. Community results of the analysis, we can conclude that the better solution for machines with fixed direction of rotation is to use instead of the radial the axial fan. For axial fan the motor temperature in the same condition was lower by about 5°C.

Modification of a Grain Moisture Conditioner into a Vacuum Steam Pasteurizer

“…Based on the calculated safety factor, the chamber can withstand an external pressure of 202.6 kPa, which is twice the atmospheric pressure limit. The simulation result was consistent with the maximum allowable external pressure (199.6 kPa) that was calculated using the ASME simplified calculations for an external pressure vessel [19].…”

“…A 400 mm space is created between the holes, which means that all the steam is concentrated at the wall of the chamber. Using Autodesk CFD 2024 [19], the steam path was simulated, the hole's locations were adjusted, and four additional holes were added to optimize the steam distribution inside the chamber. The existing holes of the hollow shaft were patched, and eight new holes with a diameter of 10 mm were drilled: four at the bottom and four at the top, with a 200 mm space between the centers of the holes (Figure 5).…”

Technical and functional analysis of Albolafia waterwheel (Cordoba, Spain): 3D modeling, computational-fluid dynamics simulation and finite-element analysis

“…For this, it was necessary to simulate the flow under real conditions and to validate the performance of the waterwheel, using finite volume calculation by computer, which is used by CFD techniques [20]. The software used was Autodesk Simulation CF, which is also used in multiphase water-air research [21,22] and other areas [23,24].…”

The Fan Design Optimization for Totally Enclosed Type Induction Motor with Experimentally Verified CFD-Based MOGA Simulations

“…The axial and radial fans were examined both experimentally and numerically to show that one of the axial fan designs improved motor efficiency while keeping the temperature constant [13]. The performance studies conducted on two separate fans to examine the cooling performance with Autodesk CFD 2013 software showed that the cooling with the axial fan was slightly lower than the radial fan [14]. The study on air gap between the stator and rotor in rotating electrical machines successfully verified the simulation outputs of six correlation equations given in the literature [15].…”
