چکیده
Abstract To enhance the heat transfer efficiency of spiral wound exchanger, a grooved exchanger (GSWHE) was proposed. A test platform accomplished to experimentally investigate performance with comparison (SWHE). The uncertainty analysis experiment conducted, maximum relative error being not more than ±5%. comprehensive coefficient GSWHE is higher that SWHE when cooling water flow rate low. determine both sides, Wilson plot method applied. tube side in found have an about ±30% compared empirical correlations. results also clearly suggest grooves shell GSWHE. By employing effectiveness as criterion, be 1.23 times SWHE.

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...

متن کاملHeat transfer enhancement in a spiral plate heat exchanger model using continuous rods
This study presents an innovative and simple way to increase the rate of heat transfer in a spiral plate heat exchanger model. Several circular cross-section rods, as continuous vortex generators, have been inserted within the spiral plate heat exchanger in the cross-stream plane. The vortex generators are located at various azimuth angles of α=30◦, 60◦, 90◦, and 120◦ with non-dimensional diame...
