An experimental investigation of R134a refrigerant heat transfer in the channels with twisted tapes inserts

Numerical and Experimental Investigation of Heat Transfer Augmentation in Double Pipe Heat Exchanger with Helical and Twisted Tape Inserts

Nowadays, heat exchangers with twisted-tape inserts have widely been applied for enhancing the convective heat transfer in various industries such as thermal power plants, chemical processing plants, air conditioning equipment, refrigerators, petrochemical, biomedical and food processing plants. In general, twisted tape insert introduces swirl into the bulk flow which consequently disrupts a th...

An Experimental Study of the Temperature Distribution In a Horizontal Refrigerant 12 Evaporator Fitted with Twisted Tapes

An experimental investigation of heat transfer of Fe2O3/Water nanofluid in a double pipe heat exchanger

One way to increase the heat transfer is to use perforated twisted tapes with different hole diameters, which largely improve heat transfer with an increase in the heat transfer area at the constant volume and more mixed flow. In the previous studies, the effect of nanofluids with perforated twisted tapes is less studied. In this work, the performance of water / iron oxide nanofluid in a double...
