Benchmarks

1. Introduction

This section details with benchmarks of the calculation of view factors. The used formula can be found View Factor:

Two examples are studied :

  • walls which form a right angle

  • parallel walls

The computation time is measure and the result is compared with the theorical exact value.

2. Angle of Walls

2.1. Presentation

wall angle
Figure 1. Geometrie of angle of wall

The following benchmarks study two walls that form a right angle. the walls dimensions are as follows:

  • length w = 1

  • height h = 1

  • depth l = 1

The formula for the calculation of the view factor between two non-parallel walls can be found view factor between two walls in angle

3. Parallel Walls

3.1. Presentation

wall parallel

The following benchmarks studies the case of two parallel walls with the following dimensions:

  • length a = 1

  • width b = 1

  • height c = 1

The used formula can be found in view factor between two parallel walls.
