Abstract

To promote the usage of potential cold energy from exhaust system of cryogenic wind tunnel

realize scientific construction and energy saving

the status and methods of cold energy recycle are discussed. The operating processes and features of exhaust system in high Reynolds number testing are introduced and the cold energy from cryogenic wind tunnel exhaust system is calculated preliminarily. Based on the process analysis of oversea cold energy recycle schemes from cryogenic fluids gasification and the technical features of domestic cold energy recycle schemes

the recovery and efficient utilization of cold energy from liquid nitrogen spray cooling in cryogenic wind tunnel are studied. Considering the technology feasibility and economical efficiency

three expected cryogenic energy recycle schemes are provided

including a storage of the exhaust energy for civil air-conditioning

re-liquefying the gaseous nitrogen through an air separation process and using solid nitrogen as the cooling source. The advantages and disadvantages of the above-mentioned three approaches are analyzed. The first scheme has a low recycling rate because of the necessary additional cold-consuming equipment; the second scheme has an acceptable recycling rate and a good economical efficiency without additional investment; the third scheme has a good recycling rate but the further higher investment. Thus an appropriate recycle scheme and a reasonable wind tunnel testing process are important for cryogenic wind tunnel exhaust energy recycling.
