The study evaluated the potential benefits of including the effects of ‘jetting’ into the ‘Hot stuff’ (HS) model in place of the pen air turnover (PAT) parameter.

The study evaluated the potential benefits of including the effects of ‘jetting’ into the ‘Hot stuff’ (HS) model in place of the pen air turnover (PAT) parameter. Jetting refers to a component of the ships ventilation where a controlled and measurable air velocity is directed across a specified area. The report determined the typical velocity ratio of an average pen and compared the use of a velocity ratio and the standard PAT within the HS model.
