Abstract

Results of numerical simulation of enclosed volume with supply and exhaust ventilation are presented. Impact of computational mesh resolution on obtained results was shown. Objective of conducted research was to evaluate impact of input mesh size on simulation results quality. An enclosed cube with local heat source, which was mimicing artificial light fixture was considered as computational domain. Numerical model was based on SST turbulence model and was formulated for a steady state problem. Temperature distribution was obtained for five considered meshes with various resolution. Statistical evaluation of obtained results was conducted with normal probability plots.

Keywords:

numerical simulation, computational mesh, normal distribution plot, heat transfer.
