Simulation of flow and thermal modeling of a headlamp in Ansys Fluent

Simulation of flow and thermal modeling of a headlamp

In the theory of radiative transfer, of either thermal or neutron radiation, a position and direction-dependent intensity function is usually sought for the description of the radiation field. The intensity field can in principle be solved from the integrodifferential radiative transfer equation (RTE), but an exact solution is usually impossible and even in the case of geometrically simple systems can contain unusual special functions such as the Chandrasekhar functions.

This tutorial is about setup and solution flow and thermal modeling of a headlamp by using discrete ordinates (DO) radiation model.

This tutorial demonstrates how to do the following:

  • Read an existing mesh file into ANSYS FLUENT
  • Set up the DO radiation model
  • Set up material properties and boundary conditions
  • Solve for the energy and flow equations
  • Initialize and obtain a solution
  • Postprocess the resulting data
  • Understand the effect of pixels and divisions on temperature predictions and solver speed

Problem Description

The geometry is shown in the picture below a simple two-dimensional section of a headlamp construction. The key components to be included are the bulb, reflector, baffle,
lens, and housing. For simplicity, the heat output will only be considered from the bulb surface rather than the filament of the bulb. The radiant load from the bulb will cover all thermal radiation. This includes visible (light) as well as infrared radiation.
