{"title":"Numerical study of radial high-pressure blower with frequency converter","authors":"V. Stoyanov, V. Nikolov","doi":"10.1063/5.0090994","DOIUrl":"https://doi.org/10.1063/5.0090994","url":null,"abstract":". Radial high-pressure air blowers are used when it is necessary to transfer air mass from one area to another accompanied by generation of significant pressure in a short period of time. In practice, this is used in case of need for rapid extraction of contaminated air or in general in the industry for intensive blowing or sucking air from or in rooms with special requirements for air quality in them. The aim of this work is to consider the specific geometry of a radial high-pressure air blower, model S-HP 470/35 - 105/20 from Elektror airsystem Gmbh, for which detailed measurements according to DIN EN ISO 5801 Fans - Performance testing are made. As a result of the measurements made for this particular blower, a detailed ventilation characteristic curve is created. The selected range for validation of the numerical results compared to the experimental measurements coincides with the range of ventilation characteristic curve from 0m 3 /min to 48.2 m 3 /min and pressure increases up to 20,000 Pa and accelerates up to 105 Hz (approx. 6,200 rpm) on the blower's impeller. For this purpose, a 3D engineering simulation model known as Computational Fluid Dynamics (CFD) and a digital twin of the real model selected for study are used. The simulations are performed in the commercial software product Star-CCM+ version 6.04.014 using the v 2 f Low-Reynolds Number k- (cid:1837) turbulence model. Finally, the numerical results are compared with the DIN EN ISO 5801 experimental measurements.","PeriodicalId":114931,"journal":{"name":"17TH INTERNATIONAL CONFERENCE ON CONCENTRATOR PHOTOVOLTAIC SYSTEMS (CPV-17)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121634669","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}

Fafard, M. Gendry, V. Aimez","doi":"10.1063/5.0103648","DOIUrl":"https://doi.org/10.1063/5.0103648","url":null,"abstract":". InGaAs lattice matched to InP is a promising material for bottom sub-cell in a 4-junction solar cell designed for concentrated photovoltaics applications. Here we compare the performances of two structures that could replace standard monolithic InGaAs homojuntion. The first one is a stand-alone solar cell realized via epitaxial lift-off (ELO) process on a flexible substrate. The second one is a heterojunction solar cell, kept on its parent InP substrate, composed of an InP emitter and an InGaAs absorber. A third structure made of an homojunction InGaAs solar cell on an InP substrate is used as reference. Under one sun illumination the heterojunction solar cell shows the highest V OC (383 mV) and fill factor. Nevertheless, when performing under concentrated sunlight the structure is limited by a lower V OC increase rate and a high series resistance compared to the ELO cell. Indeed, ELO cell shows a lower V OC (353 mV) than the two other structures under one sun illumination but, when performing under concentration, ELO cell recovers V OC and shows a lower impact of series resistance. Therefore, both ELO and heterojunction solar cell show interesting and complementary behaviors that could be interesting to associate in an ELO-heterojunction solar cell.","PeriodicalId":114931,"journal":{"name":"17TH INTERNATIONAL CONFERENCE ON CONCENTRATOR PHOTOVOLTAIC SYSTEMS (CPV-17)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116532214","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}
