In this aim both the public administrations and the technical experts need reliable calculation methodology to assess buildings’ energy performance. In this framework, despite the recent publication of the Standard EN ISO 52016, that deeply modifies the approach to the energy building simulation by introducing a new hourly dynamic calculation model, the current normative framework (EN ISO 13790) will maintain its validity until the incorporation of the new Standard in the national Standards and Decrees (such as the Italian Standard UNI/TS 11300-1) will take place. The aim of this paper is comparing the suitability of the simulation approaches proposed by the above-cited Standards in relation to their different levels of complexity and to the levels of details of the results provided by them. On purpose, a case study in which the energy behaviour of a public building, sited in the Sicilian city of Trapani in the South of Italy, will be analysed and the results of the simulations conducted according to the aforementioned Standards will be compared considering the outcomes of the EnergyPlus software as reference values.","PeriodicalId":182421,"journal":{"name":"SECOND INTERNATIONAL CONFERENCE ON MATERIAL SCIENCE, SMART STRUCTURES AND APPLICATIONS: ICMSS-2019","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128833608","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}

Facchini","doi":"10.1063/1.5138738","DOIUrl":"https://doi.org/10.1063/1.5138738","url":null,"abstract":"The aim of this work is to develop a suitable technique to measure internal heat transfer coefficient distributions of a high conductivity device (e.g. a gas turbine blade). The technique implements the acquisition of external full surface temperature data of the geometry during the thermal transient evoked by internal cooling, in concurrence with geometry material property details, part wall thickness and internal fluid temperature. With the help of an infrared camera the external temperature history of the geometry is recorded during the whole thermal transient. Infrared data is combined with cooling flow network modeling to provide the boundary conditions for a finite element model representing the geometry. An inverse transient conduction model of the geometry is executed with updated internal heat transfer coefficient distribution until the convergence is reached with the experimental measured external wall temperature at a given time. The first iteration of internal heat transfer coefficient distribution is calculated by using lumped thermal capacitance model. Then a root finding algorithm is used for further iterations until convergence is achieved. The technique is validated on a canonical test case composed by a straight circular duct. The experimental setup consists of an oven which contains ceramic heaters, an air intake system used for flowing air inside the duct and a data acquisition system consisting of Coriolis flow meter, thermocouples and an infrared camera. First the duct is heated to uniform temperature in the oven, then an air is introduced into the duct in order to induce a thermal transient. Reynolds number of 25000, 50000 and 75000 are used for different tests. The outcomes of different tests are compared with available literature data, obtaining a good agreement and thus validating the employed experimental approach.The aim of this work is to develop a suitable technique to measure internal heat transfer coefficient distributions of a high conductivity device (e.g. a gas turbine blade).

In this work, a data-driven Bayesian Hierarchical Model (BHM) is employed to perform a probabilistic prediction of gas turbine future behavior. The BHM approach is applied to field data, taken from the literature and representative of gas turbine degradation over time for a time frame of 7-9 years. The predicted variable is compressor efficiency collected from three power plants characterized by high degradation rate. The capabilities of the BHM prognostic method are assessed by considering two different forecasting approaches, i.e. single-step and multi-step forecast. For the considered field data, the prediction accuracy is very high for both approaches. In fact, the average values of the prediction errors are lower than 0.3% for single-step prediction and lower than 0.6% for multi-step prediction.","PeriodicalId":182421,"journal":{"name":"SECOND INTERNATIONAL CONFERENCE ON MATERIAL SCIENCE, SMART STRUCTURES AND APPLICATIONS: ICMSS-2019","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116674211","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}
