Since the cold generation process in adsorption refrigeration systems is not continuous, an evaporator must be designed to produce the maximum amount of ice possible without reaching very low temperatures inside the evaporator. Obtaining the temperatures at the evaporator outlet and the areas on which they depend are the basis of this study. For different diameters of the cylindrical evaporator and different thicknesses of the ice layer, the convective heat transfer coefficients, the thermal resistance on the evaporator walls and the methanol temperatures inside the evaporator were evaluated. The most suitable evaporator dimensions were chosen according to the thermal analysis performed.","PeriodicalId":272476,"journal":{"name":"2021 3rd International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116094117","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}

The usage of fossil-fired steam superheating with reduced initial parameters of the primary and secondary circuits in the thermodynamic cycle of a nuclear power plant with a VVER-1200 reactor makes it possible to increase the energy efficiency and safety of nuclear power plants by increasing the nuclear fuel burnup, as well as the absence of the need to manufacture expensive high-pressure vessels for reactors.

Sparse code multiple access (SCMA) is one of the most efficient NOMA implementations. The SCMA method is based on the use of codebooks – sets of sparse signals. The structure and content of codebooks determines the communication rate and interference immunity. This paper describes the transmission of communication system signals to SCMA in multipath communication channels with a frequency selective fading. The method of codebooks adapting for transmission channel state has been proposed. The bit error rate (BER) performance of this method has been estimated for various channel models corresponding to 5G FR1 systems and for various channel estimation accuracy. The effectiveness of the proposed method has been shown. The research results can be applied in other NOMA systems.","PeriodicalId":272476,"journal":{"name":"2021 3rd International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123608725","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}

From this cold spot, the cooling front can propagate along the cooled surface with transition to the more intensive heat transfer regime. According to the results of the experiments, the jet leads to significant disturbance of cooling uniformity with an increase in surface temperature at vapor film collapse (transition temperature).","PeriodicalId":272476,"journal":{"name":"2021 3rd International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127728344","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}
