Client:

Client is a leader in the renewable energy industry in Wind and Solar, working to provide the world's best offshore/onshore wind turbines.

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.

Scope:

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
