Heat transfer is one of the main concerns in industries. Corrugated type heat exchangers are one of the best options available for heat transfer in less space. Many researchers have worked for corrugated plate heat exchanger with configuration corrugation angle of 30°. In the present work, corrugated plate heat exchanger with 30° corrugation angle has been modeled and results have been compared with that of the base paper. Further the corrugation angle has been changed to 45°. The boundary conditions have been kept same as that for 30°. Heat transfer rate, Nusselt number, Reynolds number, Friction factor, Paclet number and their variation have been found out for the new geometry. Graphical plots, variation in temperature and water velocity streamlines have also been found out.

This work includes the effect of different working fluid on the performance of heat exchanger. For analysing the effect of different working fluid, it considered air, water and different nanofluids and measure the Nusselt number and friction factor for each case. It also analysed the effect of change in Reynolds number on the performance of heat exchanger for different working fluids. For analysing the effect of change in Reynolds number, it considered four different Reynolds numbers that is 10000, 12000, 14000 and 16000. For performing the numerical analysis ANSYS fluent was used. Through numerical analysis it is found that for air as a working fluid heat transfer is less, whereas in case of water it is marginally higher than the air. But for all nano fluids, heat transfer is much higher than the air and water. For analysing the effect of different nano fluid, this work includes three nano fluids that are Al2O3, TiO2and ZrO2. Through analysis it is concluded that heat transfer is more in case of TiO2 as compared to other nanofluids, air and water. With increase in Re number heat transfer gets increase whereas as friction factor get decrease.

Exam Problem #8 (Finding Friction Loss)

Exam Problem #8 (Finding Friction Loss)

Question

A pump provides 1,500 gallons per minute of coolant through a steel 6″ diameter pipe that runs to and from the coolant reactor which is 450 feet away. The coolant reactor has an equivalent length of 115 feet of pipe. On the way to the reactor the coolant must pass through 4 90º elbows and 2 swing check valves.

If the coolant has a kinematic viscosity of 1.684e-5 ft2/s how much head must…
