Heat transfer through a radiator

1
Heat transfer through a radiator

• Simulation of a water cooled radiator with air
  flowing through it at 20 m/s using Starccm
• By Scott DuBois
• MeEn 340
• Heat Transfer Project 2014

Setup

• Velocity of air 20 m/s
• Mass flow of water 1.8 Kg/s
• Temp. of surrounding air 308 K
• Initial Temp. of water 380 K
• Physics continuum
• Three Dimensional, Steady, Gas, Segregated Flow,
  Constant Density, Turbulent, RANS, K-Epsilon
  Turbulence
• Mesh continuum
• Surface Remesher and Trimmer
• Objective Use Starccm to find the amount of
  Heat Transfer through a radiator and plot the
  temperature gradient
