ABSTRACT: This paper performs a simulation study of the heat transfer phenomena in a
tubular U-loop pipe. We have investigated the enhancement of heat transfer
with mass flow in a pipe without insert, with full length and short length
twisted tape inserts. The length of the pipe is approximately 2436.80 mm long
with 29 mm inner and 33 mm outer diameter respectively. A constant heat
flux is taken which generated the boundary layer of the pipe close to the flowing
fluid around the boundary. The simulations are considered for the stationary
and the time dependent module for 35 seconds with different length of
inserts. The comparisons are made among the results. We observed that the
transfer of heat is enhanced significantly with the increase of the length of inserts
inside the computational domain. We also found that, full length twisted
tape inserts are more effective than comparing with the short length inserts
and without insert.
