Qualitative wind tunnel studies are often just as important as quantitative ones. In some cases, they’re more so! Many techniques have been developed to “see” the airflow over a test model. These include yarn tufts, colored oils and smoke.
AEROLAB now offers propylene glycol as an alternative to white mineral oil.
AEROLAB’s electric-powered Smoke Generator produces thick white smoke. Although originally developed for wind tunnel testing, the system has been used in other applications such as heating and ventilation, medical research and automotive design.
