This challenge leads to the search for high-performance compact heat exchanger as one of the thermal management solutions. Conventionally manufactured heat exchangers had limitations that thwart the development of geometrically complex heat exchangers which are capable of exploiting topological aspects to enhance thermal performance. Subsequently, additive manufacturing (AM) is proposed as a powerful fabrication technique for compact heat exchanger based on the mathematically known triply periodic minimal surfaces (TPMS). In this work, we present 3D compact crossflow heat exchanger computational fluid dynamics (CFD) modelling of geometrically complex structures based on TPMS using STARCCM+ CFD platform. Moreover, CFD modelling is used to obtain new characteristics maps that relate heat transfer effectiveness (Ɛ) and number of transfer units for the proposed heat exchanger. The convection heat transfer coefficient, pressure drop, and inlet and outlet fluid temperature are all examined.</p></div>","PeriodicalId":100472,"journal":{"name":"Energy Storage and Saving","volume":"1 3","pages":"Pages 153-161"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772683522000218/pdfft?md5=ab74d94c48502b041df27a042edc4fe8&pid=1-s2.0-S2772683522000218-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72031243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Along the confined flow path of the heat exchanger, the frosting at downstream is affected by the parameters from the upstream. In this study, a numerical model considering the confinement effect has been proposed to predict frosting characteristics in plate-fin heat exchanger. Convection-diffusion equations for humid air and empirical correlations for local frost density are employed in the numerical prediction. Frosting behavior and heat transfer in the confined channel are investigated with different humid air parameters and cold surface temperatures. The results indicate that frost thickness in the confined channel is thicker than that in open space under the same inlet parameters. The frost layer is thicker and fluffier along the confined channel. In addition, the air temperature difference between inlet and outlet of the confined channel enlarges with frosting. Under the same average temperature of upper and lower surfaces, the heat and mass transfer of frosting are enhanced with diminishing temperature difference of upper and lower surfaces. In such condition, frosting is mainly influenced by the cold surface with the lower temperature.</p></div>","PeriodicalId":100472,"journal":{"name":"Energy Storage and Saving","volume":"1 3","pages":"Pages 136-147"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772683522000127/pdfft?md5=1838145b1757afcab10fc75d08326d43&pid=1-s2.0-S2772683522000127-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72031247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The novelty of this study relies on the definition of a pyrolytic polygeneration process to simultaneously attain an energy-type product and abiochar to maximize the versatility of the products and their usage. To this aim, the heating value of the gas and its potential to feed a micro combined heat and power (micro-CHP) system was evaluated. Additionally, the resulting biochar was chemically activated and tested as adsorbent for the removal of contaminants from an aqueous solution. Results show that the pyro-gas from the shell-type residue was suitable to be used as feed stream in a micro-CHP unit, which was able to operate near the full-load (91.9%) with electrical and thermal efficiencies of 27.6% and 57.9%, respectively. In the case of the biochar fraction, poor results were found for the char prior to activation. Instead, once it was activated with KOH, the resulting activated carbon presented high effectiveness as adsorbent and complete removal of the measured compound (methylene blue) was achieved.</p></div>","PeriodicalId":100472,"journal":{"name":"Energy Storage and Saving","volume":"1 3","pages":"Pages 129-135"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772683522000206/pdfft?md5=adf1e6e0b69f1c9d35e35a3219434691&pid=1-s2.0-S2772683522000206-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72031248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Renewable energy system offers enormous potential to decarbonize the environment because they produce no greenhouse gases or other polluting emissions.

To account for these intermittencies, renewable energy can be stored using various techniques and then used in a consistent and controlled manner as needed.
