Double pipe heat exchanger with lubricant and water liquid
Best insight from top research papers
A double pipe heat exchanger can be used with a lubricant and water liquid. The use of nanofluids, such as Al2O3 and TiO2 nanoparticles mixed with deionized water, has been investigated to improve the performance of the heat exchanger. Experimental results have shown that the addition of nanoparticles increases the heat transfer rate, convective heat transfer coefficient, overall heat transfer coefficient, Nusselt number, and Reynolds number. The highest values were obtained with a volume concentration of 0.3% and a flow rate of 4.5 L/min in Al2O3/water nanofluid . Another study utilized CuO nanoparticles with volume concentrations of 0.5% and 1% in water as the working fluid in a counter flow double tube heat exchanger. The use of nanofluid resulted in improved heat exchanger effectiveness, with maximum values of 40% and 54% for the respective volume concentrations .

What is a heat pipe for heating water?5 answersA heat pipe for heating water is a device that utilizes the principles of heat transfer to transfer heat from a source to the water. It typically consists of a pipe with a working fluid inside, such as ethanol or water, which undergoes a phase change from liquid to vapor and back again to transfer heat efficiently. The heat pipe can be designed with different diameters and lengths, and may include additional components such as condenser sections and evaporator sections. The efficiency of the heat pipe can be improved by optimizing its design and operating conditions, such as the fill charge ratio and the length of the evaporator. The use of heat pipes in water heating systems has been shown to increase overall system efficiency and performance, resulting in higher water temperatures and energy gain. The theoretical predictions of heat pipe performance have been found to be in good agreement with experimental values.
Why water can be used for cold fluid in heat exchangers?5 answersWater can be used as a cold fluid in heat exchangers due to its high specific heat capacity and density, which allows it to receive, store, and carry higher amounts of energy compared to air. Water's incompressibility and low specific volume also require smaller amounts of mechanical work for fluid circulation. Additionally, water has desirable thermal transport properties that make it a viable alternative to traditional refrigerants in heat pipes, enhancing the effectiveness of the arrangement. The heat transfer performance of a cold-water phase-change heat exchanger is significantly affected by changes in the intermediary side inlet water temperature, intermediate water flow rate, and cold water flow rate. Water is also used as heat exchange water in cooling systems to prevent oxidation and deterioration of metal materials, suppress the growth of algae and microorganisms, and reduce environmental impact. Overall, water's properties and characteristics make it an ideal choice for cold fluid in heat exchangers.
