However modeling of a CLPHP system in GAMBIT has many challenging issues due to the complexity and multi-physics nature of the system. So, the closed loop pulsating heat pipe modeled here has no wick material inside it as it present in heat pipe. The closed loop pulsating heat pipe has no complex structure so it is to be modeled. Flow visualization was conducted for the closed loop pulsating heat pipe using ANSYS Fluent 13.0. With appropriate boundary conditions we can visualize the behavior of the model and make predictions regarding its performance. Water-water vapor and ethyl alcohol ant ethyl alcohol vapor are taken as the working fluid and heat flux is supplied at the inlet. Phenomena such as nucleation boiling, formation of slug and propagation of inertia wave were observed in the closed loop PHPs. Also the analysis has been done to know the behavior of CLPHPs under varying supply of heat flux at the inlet (evaporator).for this, the output heat flux is obtain at outlet (condenser) and find out how the heat flux is varying for different heat flux and the different working fluid.","PeriodicalId":217317,"journal":{"name":"Heat Pipe Science and Technology, An International Journal","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129285875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermophysical properties of water as a working fluid and high thermal conductivity of copper as a constructional material for a body and a wick as well as their good compatibility make it possible to achieve an extremely high heat flux and low thermal resistance of such LHPs. Today the obtained values of these parameters are close to 900 W/cm and 0.04 °C/W, respectively. However, making copper-water LHPs one has to overcome a serious contradiction between the high thermal conductivity of copper and the low value of T P d d which water has at a temperature below 100 °C. Computer simulations and experimental investigations of copper-water LHPs have shown that despite the mentioned contradiction achievement of high performance characteristics is possible with optimal choice of design parameters of devices. The paper presents results of development, experimental and numerical investigations of LHPs made entirely of copper and supplied with a cylindrical and a flat evaporator with water as a working fluid. Examples of the use of the given devices in cooling systems of different electronics are shown here.","PeriodicalId":217317,"journal":{"name":"Heat Pipe Science and Technology, An International Journal","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130148206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
