A local ventilation solution for mould casting area was designed and dimensioned with the aid of Computational Fluid Dynamic (CFD)-calculations. According to the calculations, the most efficient solution in this case was a push-pull ventilation syste

When a person is in a unidirectional airflow and the contaminant source is wihtin the wake region, high exposure can occur. This work studied the effects of freestream velocity and convective heat release rate on the exposure both experimentally and
