With the gradual increase of applications, more and more equipments work in a non-static state, but there is little research under rolling conditions. Therefore, it is necessary to investigate the influence of rolling motion on the nucleate pool boiling process. In this study, a numerical investigation of the nucleate pool boiling process under static and rolling conditions is performed based on the volume-of-fluid (VOF) method. Physical fields and phase distribution under static state and rolling motion are compared to investigate the effect of rolling motion on the nucleate pool boiling process. The results show that rolling motion greatly influences the bubble behavior and void fraction owing to the differences between flow fields. The void fraction decreased by 11.84%, 48.82%, and 56.87% as the maximum rolling angle increased from 15° to 45°, and by 11.84%, 22.27%, and 21.81% as the rolling period increased from 1 s to 3 s. The void fraction decreased by 11.84%, 48.82%, and 56.87% as the maximum rolling angle increased from 15° to 45°. The heat transfer coefficients of different cases are compared, and it is found that the effects of rolling motion on heat transfer coefficients can be ignored.</p></div>","PeriodicalId":100472,"journal":{"name":"Energy Storage and Saving","volume":"2 1","pages":"Pages 336-347"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49884194","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}

Particular focus was placed on the lanthanide, alkaline earth metals, redox-active transition metal, and non-redox active Group 3 metals. The review suggests that a small ionic radius lanthanide on the A-site can increase the size discrepancy, leading to Mn-O<sub>6</sub> octahedra tilting and more facile Mn-O bond breaking. Doping the A-site with a divalent alkaline earth element can increase the valance of the transition metal, leading to greater reduction capabilities. A transition metal with one electron in the e<sub>g</sub> orbital is the most effective for reduction while for oxidation, zero electrons in the high-energy e<sub>g</sub> orbitals is optimal. Finally, doping of the B-site with metals such as gallium or aluminium aids in sintering resistance and allows reactivity to remain constant over multiple cycles. Higher reduction temperatures and moderate re-oxidation temperatures also promote higher fuel yields as does the active reduction of the perovskite under hydrogen, although the total energy consumption implications of this are unknown.

The enthalpy-porosity method, local thermal non-equilibrium model and Darcy-Forchheimer law are comprehensively considered to describe the convective heat transfer process in porous media. The modified model is then validated by benchmark data provided by particle image velocimetry (PIV) experiments. The phase change behavior, heat transfer efficiency and energy storage performance are numerically investigated for different partial porous filling strategies in terms of filling content, position, height of porous foam and inclination angles of cavity. The results indicate that due to the resistance in porous region, the shear stress exerted by the main vortex (natural convection) in pure fluid region and the momentum transferred, a secondary vortex phenomenon appears in the porous region near the fluid/porous interface. Moreover, such discontinuity of permeability and fluid-to-porous thermal conductivity results in the cusp of phase change interface at the horizontal fluid/porous boundary. Among four partial porous filling cases, the lower porous filling one has more desirable heat transfer performance, and the 3/4H lower porous filling configuration is the best solution for optimization of the latent heat thermal energy storage (LHTES) systems. For tilted cavity, the increase of inclination angle positively affects the heat transfer efficiency as well as the energy storage rate of the LHTES system, where the performance of 3/4H lower porous filling configuration is further highlighted.</p></div>","PeriodicalId":100472,"journal":{"name":"Energy Storage and Saving","volume":"1 4","pages":"Pages 293-308"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772683522000279/pdfft?md5=3d8377b58149f9df9b96c53f3130eb52&pid=1-s2.0-S2772683522000279-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72073057","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 model was able to predict engine performance parameters, NO emission, and engine knock at different engine operating conditions including inlet pressure, compression ratio, and excess air factor. Engine knock was prevented by increasing the excess air factor up to 1.2 when the engine operated with higher inlet pressure and compression ratio. It was found that a maximum inlet pressure of only 120 kPa could be used with an engine compression ratio of 14 and excess air factor of 1.2 for knock free operation. The peak engine power was produced when the engine operated with an inlet pressure of 200 kPa and compression ratio of 8 or 9. It was also found that the optimum operating condition which resulted in high engine power accompanied with low fuel consumption and high efficiency was obtained when the engine operated with an inlet pressure of 180 kPa and a compression ratio of 11.
