Iranian researches from Ferdowsi University of Mashhad in association with their counterparts from University of Malaya, Malaysia, studied the effect of presence of nanoparticles in increasing the efficiency of cooling devices used in various industries, including power plants, petroleum industry, gas, and petrochemicals.
Increasing Efficiency of Cooling Devices in Oil, Gas Industries
Tehran, Iran | Posted on February 21st, 2015The cost of energy consumption can be decreased using the results of the study.
Energy saving is the most important plan in various industries. Therefore, this project was defined for the optimization of energy consumption in two-phased thermal pipes. To this end, a new fluid has been synthesized with high heat transfer efficiency. The fluid has a multi-layered graphene base that is synthesized through microwave method.
According to the researchers, the project tries to increase the power of heat transfer and can reduce the price of two-phased thermal pipes or reduce the number of pipes. On the other hand, thermal cycles can be operated at lower temperatures, which definitely results in reduction of energy consumption.
Water and many important fluids have very low heat transfer coefficient in industrial processes. According to the evaluations carried out by the research group, multi-layered graphene has very high heat transfer coefficient, and its combination with water can overcome the weak point of water in heat transfer. The problem in the application of graphene is its unwillingness to be homogenously dispersed in aqueous media. Proposed methods to overcome the problem have so far been very time-consuming and costly. In this research, the edges of graphene have been combined with hydrophilic agents through microwave method, and a homogenous fluid has been produced, which has very good performance in heat transfer even in low weight concentrations.
Results of the research have been published in Energy Conversion and Management, vol. 92, issue 1, 2015, pp. 322-330.
