Why APA?

APA team is highly experienced in performing conjugate heat transfer simulations using computational fluid dynamics technology for steady state and turbulent flow problems.


The scope of work is to perform computational fluid dynamics analysis for 1500V inverter room and study the temperature distribution and ensure the average temperature rise (ΔT) ≤ 5˚C while the site ambient temperature is 50˚C.

Simulation Process:

  • ● Geometric clean-up of the inverter converter package along with Fan and porous media region
  • ● Creation of CFD domain & mesh for inverter converter package with very fine mesh to accurately capture the boundary layer effect
  • ● Setting up SST K-Omega Turbulence Model
  • ● Modelling of Solar Radiation with Heat flux boundary conditions on walls
  • ● Predicting the baseline design’s performance parameters such as flow pattern, velocity vectors, velocity and temperature contours
  • ● Calculating Volumetric average temperature of the inverter room
  • ● Perform simulation for the proposed duct layout and optimize of the Duct opening size to arrive at the desired reduction of Volumetric average temperature
  • ● Determine whether the average pressure drop inside the inverter room is within the acceptable limit
  • ● Tabulation of inverter Room inlet & outlet air handling summary
  • Temperature distribution across the container
