Abstract

The differential pressure method is widely used nowadays for air leak detection. In this method, a master tank, which is leak-tight, and a work/ tested tank are simultaneously charged to a certain pressure and then closed from each other. If there is air leak in the tested tank, the air leak can be detected from the differential pressure occurs between the two tanks. However, the detection process becomes inaccurate since the differential pressure occurs due to the unbalance of temperature recovery in the two tanks after charging process. Although, if the tested tank is leak-tight. This problem has become the major concern in this research, as we have investigated how this unbalance of temperature recovery influenced the differential pressure between the two tanks due to some different parameters, such as charging impedance, tank volume and heat transfer coefficient. The experiment result showed a good agreement with the simulation data.
