It absorbs solar radiation to create stack effect to induce air flow for ventilation. To model air flow and heat transfer inside solar chimneys, numerical models based on Computational Fluid Dynamics (CFD) have been broadly employed. The size of the computational domain is one of the factors influencing computed results from CFD models. In this study, we investigated effects of the extension of the domain above the outlet of the air channel as the gap and the height of the air channel changes. Two types of the computational domains were studied. The small domain has identical physical size with a cavity inside the solar chimney while the large domain contains both the cavity and the ambient air surrounding the chimney. The induced flow rate and temperature rise of the chimney were computed and compared between those domains. It is seen that to ensure the changes of both flow rate and temperature below 1.0%, the required extension, h, of the domain above the outlet of the air channel is a function of the gap – to – height ratio G/H, not only the gap. Specifically, for G/H in the range of 0.1 – 0.4 in this study, the required h/G rises from 10 to 30.","PeriodicalId":253890,"journal":{"name":"1ST VAN LANG INTERNATIONAL CONFERENCE ON HERITAGE AND TECHNOLOGY CONFERENCE PROCEEDING, 2021: VanLang-HeriTech, 2021","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131866717","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 syngas production from the gasification of rice husk can also be supplied to the dual-fuel diesel engine, saving oil consumption. The operating conditions are key contributions to obtain the high syngas qualification and high ratio of the replaceable syngas fuel in the diesel-syngas engine. This paper presents the effect of air velocity (from 2.0 to 8.0 cm/s), bulk density (from 92.31 to 122.55 kg/m3), and moisture of rice husk (from 4.0 to 13.0 %) on the replaceable diesel oil ratio and power capacity of the dual-fuel diesel engine RV-125N, using the downdraft gasifier. The obtained results indicate that at the moisture of 4.3 % of rice husk, the bulk density of 101.86 kg/m3, and the air velocity of 6.0 cm/s, the power capacity can reach 1.41 kW and the replaceable diesel oil ratio was over 60 %.

The objective of this article is to report our survey works done in April 2016, in view of authenticity in preservation work. Methods used include site-survey on roof-tiling materials and roof- tile production named ‘Marseillaise Acier’ produced by Acier upon Marseilles typology, where two types of tiles found: (1) Maltese Cross, Arnaud Etienne et Cie, Marseille St. Henri, France; and (2) Bee, Guichard Carvin et Cie, Marseille St. Andre, France. As time went by, other two types of tiles were found to be used, named ‘Wang Tai’ and ‘Tuileries de L‘Indochine’. Due to the demand of roof-tiling replacement, resulted in changes to the roof structure load bearing, analysis options on weight and load bearing variables were considered and compared for possible solutions with new tiles impored from Monier-France tile producer due to ist heavier weight and large dimension. Research limitation and implications is limited to our real case at the cathedral, in which we proposed to re-collect old but reusable roof-tiles to a particular roof location for the sake of authenticity.","PeriodicalId":253890,"journal":{"name":"1ST VAN LANG INTERNATIONAL CONFERENCE ON HERITAGE AND TECHNOLOGY CONFERENCE PROCEEDING, 2021: VanLang-HeriTech, 2021","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130545453","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}

Many techniques have been introduced to research on solar chimneys such as experimental, analytical, computational methods. Recently, with the development of computer technology, computational method, particularly, Computational Fluid Dynamics (CFD) becomes more common and widely applied in solar chimney, but this method still exists limitation. One of the main limitations is using much computational source. In this study, CFD was combined with Adaptive Neuro-Fuzzy Inference System (ANFIS) to prevail against this limitation when predicting flow field and mass flow rate in a chimney. In particular, the fluid flow and heat transfer in chimney were simulated with CFD to create dataset. Two ANFIS models were built, trained, and validated using dataset from CFD. After the training, ANFIS models can predict flow temperature, velocity and induced mass flow rate, respectively, with R-squared (R2) of 0.97, 0.997 and 0.9996 for training set, while 0.9715, 0.994 and 0.9996 for testing set; similarly, root mean squared error (RMSE) are 0.032, 1.703, 3.45x10−5 for training set, and 0.042, 1.713 and 2.95x10−5 for testing set.
