HEAT TRANSFER OF ORTHOGONAL-MODE RECIPROCATING TUBE FITTED WITH TWISTED-TAPE

摘要

This article describes the results of an experimental study aimed at revealing the heat transfer physics of a twisted-tape insert in a uniformly heated tube for transitional and turbulent flow situations when the test tube remains stationary and reciprocates. Dry air is used as the test study is motivated by the need to understand the effectiveness of twisted-tape inserts n the heat transfer augmentation when applied to the piston cooling of a compression-ignition engine.
