“…Figures [4][5][6] also show that, for variations of heat load, higher heat load affects the increasing of evaporator, condenser, and adiabatic temperatures until isothermal condition is reached. It can be seen that the increasing of heat load after stable temperature distribution achieved would not affect the recurrent of overshoot phenomena, but only on recurrence of zigzag and stable phenomena and the increasing of the overall heat pipe temperature.…”

To enhance the thermal safety in case of station blackout, a wickless-heat pipe is proposed as an alternative passive cooling system technology to remove decay heat generation in the nuclear spent fuel storage pool. The objectives of this research are to investigate the heat transfer phenomena in vertical straight wicklessheat pipe using Graphene nanofluid working fluid and to study the effect of Graphene nanofluid on the vertical straight wickless-heat pipe thermal performance. The investigation was conducted in 6 meters height and 0.1016 m inside diameter of vertical straight wickless-heat pipe. In this research, the Graphene nanofluid with 1 % of weight concentration was used as working fluid. The effect of working fluid filling ratio, evaporator heat load, and coolant volumetric flow rate on the water jacket were studied. The results showed that the heat transfer phenomena, which were indicated by an overshoot, zigzag, and stable state, were observed. Based on thermal resistance obtained, it was shown that the vertical straight wickless-heat pipe charged with the Graphene nanofluid has a lower thermal resistance compared to one with demineralized water. The thermal resistance of vertical straight wickless-heat pipe using Graphene nanofluid and demineralized water were 0.015 °C/W and 0.016 °C/W, respectively. While the best thermal performance was achieved at a filing ratio of 80 %, higher heat load, and higher coolant volumetric flow rate. It can be concluded that Graphene nanofluid could enhance the thermal performance of vertical straight wickless-heat pipe.

“…There are also solar-powered humidification-dehumidification (HDH) desalination systems (El-Fiqi et al, 2007) and industrial waste heat (Gude, 2011), and solar-driven membrane distillation (He et al, 2015). (Kusuma, Putra and Respati, 2018) study modified the existing desalination system by adding thermosyphons. The results show that the use of thermosyphons in cascade solar desalination systems can increase the efficiency of the thermal system up to 2.35 times.…”

It is necessary to utilize desalination technology to clear the water available, including seawater, to meet the increasing need for clean water due to population growth. Several desalination methods, such as thermal methods, membranes, freezing g, and ion exchange, continue to be developed but have not overcome some deficiencies. Therefore, new alternative desalination methods with droplet atomization, which utilizes the air entrainment phenomena, are being developed. Research on non-dimensional fluid atomization is the basis for designing this method. The study used brine pumped through a nozzle with a small diameter to become mist or vapor. This study carried out variations of research parameters on the configuration of the experimental apparatus in the form of pressure, the diameter of the nozzle, and the number of nozzles. Quantitative data from experimental results obtained from measurement instruments and qualitative data in videos obtained using a camera are to be processed into quantitative data using image processing. The results showed that pressure affects the characteristics of a full cone-shaped water spray. It was found that the best spray system configuration with two nozzles with a diameter of 0.5 mm in a pressure of 9 bar.

“…Those studies revealed that the heat pipe could be adapted its shape to the heat source geometry that existed. Whatever its heat pipe type, it can absorb and release heat well to the environment, or the heat that is sunk can be used as another energy generator (for example, it is used as a heat source in thermal desalination) [4,[12][13][14][15].…”

To improve safety and normal operation aspects to be more economical, the NuScale type power reactor has the potential to be added passive cooling system technology. The technology is a loop heat pipe (LHP) with a wick made of a collection of capillary tubes. To determine the thermal performance of the LHP technology properly, the supporting analysis was needed before the experiment is carried out. One of the necessary supporting factors were to know the accuracy of measuring the temperature distribution on the LHP. The objective of this study was to determine the value of the uncertainty of the thermocouple used in the LHP experiment. By knowing the accuracy of the measurement of the temperature distribution, it is hoped that the resulting data is good and accurate. Data measurement was carried out using the National Instruments data acquisition system. The temperature distribution data retrieval was carried out under the condition that the LHP was in a steady state at the temperature of the hot water as the source of the LHP temperature of 35˚C, 45˚C, 55˚C, and 65˚C. Data collection was carried out within approximately 10 hours of the LHP experiment. The recorded temperature distribution data is then compared with temperature data using a well calibrated derived standard thermocouple. The calculation of the uncertainty value is carried out by statistical methods commonly used to determine the uncertainty of the temperature distribution measurement. The measurement results show that the average temperature value obtained is within the range of the standard uncertainty values of the thermocouple used. The uncertainty value obtained at all measurement points on variations in hot water temperature have value below the standard uncertainty value of the derived standard thermocouple used, which is 0.1°C. Based on these results, it can be concluded that the thermocouple used in the LHP experiment is feasible and has very good accuracy so that it can produce accurate and good LHP temperature distribution data.
