EXPERIMENTAL INVESTIGATION OF HEAT TRANSFER OF SUPERCRITICAL FLUID FLOWING IN A TUBE WITH TWISTED TAPE

Abstract

An experimental study is introduced in this investigation to analyses the behavior of heat transfer in a cooled upstanding turbulent inflow environment of supercritical carbon dioxide. A combination of the method is utilized in dealing with empirical data obtained by a perpendicular tube with bending tape applied in the test model. In presenting the results, we adopted a common method 'the dimensionless constitution' throughout experimental procedures. Also, a development toward the correlation between the parameters is achieved for upward and downward inflows. The obtained outcomes could be supported and fill a gap presents in the previous studies on turbulent perpendicular composite heat load based on cooled circumstances. The empirical outcomes present the impact of buoyancy forces on the heat transfer operation. The recommendation of the present work is the develop a numerical model for supercritical CO2 gas cooling in a tube with twisted tape.
