ABSTRACT

ABSTRACT: One of the most important application of cryogenics includes the transfer of cryogenic fluid from storage site to its utilization. To optimize the initial phase of cryogenic heat transfer, twisted channels are coated with different coating materials, which increases the chill down efficiency of cryogenic systems. Applications of coating materials like graphene, CNT, polyurethane and Teflon on twisted channels has significant time saving in cool down compared to conventional channels surfaces. Computational study was performed to evaluate the enhancement of heat transfer and coating effectiveness on chill down time. The chill down of two surfaces uncoated and coated is compared and latter one is found to be more efficient.
