Abstract

In this paper, experimental result of cryogenic chilldown of ½” stainless steel cryogenic ball valve is reported. Experiments were done on horizontally placed test section. The test section is insulated by using nitrile rubber for reducing the heat inleak.LN2 is used as the working fluid. Liquid nitrogen is feed in to the test section by using external pressurization technique. Experiments were conducted for two sets of inlet supply pressure (7.5 psi and 12.5 psi).The mass flow rates obtained for two inlet pressures conditions are 2.292 g/s and 3.31 g/s. The experimental results show that the chilldown time of valve body is higher due to its high thermal mass and chilldown time decrease with increase in supply pressure at the inlet.
