The recent trend application of the nanofluids is used in some industrial equipment such as tube heat exchanger, double pipe exchanger and shell-tube type heat exchanger. The Triangle tubes may be used in the heat exchanger. Thus, this experimental study reports the convective heat transfer performance of the aluminum oxide-water nanofluids flowing in the triangle channel. In this study, the amount of the volume fraction of the Al 2 O 3 used was 0.1 %, 0.2 %, and 0.3 respectively in base-water as the nanofluids and the Reynolds numbers were varied from about 1000 to 7000. The channel was heated by the electric wire coiled along the channel with constant heat flux. The length and the hydraulic diameter of the triangular channel were 750 mm and 7.1 mm respectively. The DC variable speed pump was used to drive the nanofluids in the channel. Five thermocouples were soldered at the outer surface of the channel to measure the surface temperature. At the inlet and outlet of the channel were attached the thermocouples to measure the inlet and the outlet temperature of the nanofluids. The heat absorbed by the fluid was then released in the cooling tower which used an induced draft fan to convince that the nanofluids temperature decreased before entering the inlet section of the channel. The heat transfer characteristics of the nanofluids are compared to that of pure water. The results show that the heat transfer increase with the increase of the Reynolds number and the volume fraction. The increase of heat transfer varies from about 11% to 36%.

This is a new era where the world’s energy consumption is so high and is likely to increase over 60% of current consumption by the year 2030. Therefore, renewable energy should be used most frequently. The most preferred alternative to fossil fuels is solar energy but converting solar energy into usable form is the most challenging part. The conversion to thermal energy is the one option. In the area of solar thermal power generation, a solar parabolic trough (SPT) collector is an effective method. Also, the use of passive methods to enhance the thermal performance of these parabolic trough receivers is currently the researcher’s interest This review study is focused on different types of geometrical modification (Artificial roughness) used to enhance the thermal performance of SPT receivers. Based on the extensive study it has been found that conical strip insert is a very broad field for research as it can enhance the thermal performance up to 5–10 times. Also there are parameters associated with the conical strips like shape, pitch, angle of twist, slant angle, geometry angle, etc. which can contribute to better performance when used in SPT receiver.
