At nine different loading direction angles, the oil\u2013bush interface temperature profiles, oil outlet temperature, maximum bush temperature, total flow rate, and oil flow rate through each groove were measured for variable applied load and oil supply pressure while the feeding temperature was kept constant (40\u00b0C). To the authors\u2019 knowledge, this is the first study of the influence of loading direction on the performance of journal bearing with two axial grooves in which the flow rate were measured in each groove for different working conditions under laminar regime. It was found that the variation of loading direction has a strong effect on the bearing performance. Under some running conditions, negative lubricant flow rate (hot oil reflux) at one groove was detected. This seldom-reported phenomenon was found to affect the bearing performance dramatically. Increasing supply pressure yielded a temperature decrease, especially for high loads, and sometimes prevented the occurrence of hot oil reflux.<\/jats:p>","DOI":"10.1177\/1350650111401970","type":"journal-article","created":{"date-parts":[[2011,5,7]],"date-time":"2011-05-07T14:09:53Z","timestamp":1304777393000},"page":"245-254","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":19,"title":["An experimental study of the influence of loading direction on the thermohydrodynamic behaviour of twin axial groove journal bearing"],"prefix":"10.1177","volume":"225","author":[{"given":"A Arab","family":"Solghar","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, School of Engineering, Shahid Bahonar University, Kerman, Iran"}]},{"given":"F P","family":"Brito","sequence":"additional","affiliation":[{"name":"CT2M, Center for Mechanical and Material Technology, University of Minho, Guimar\u00e3es, Portugal"}]},{"given":"J C P","family":"Claro","sequence":"additional","affiliation":[{"name":"CT2M, Center for Mechanical and Material Technology, University of Minho, Guimar\u00e3es, Portugal"}]},{"given":"S A Gandjalikhan","family":"Nassab","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, School of Engineering, Shahid Bahonar University, Kerman, Iran"}]}],"member":"179","published-online":{"date-parts":[[2011,5,6]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"414","article-title":"Thermohydrodynamic analysis of cooling effect of supply oil in circular journal bearings","volume":"105","author":"Mitsui J.","year":"1983","unstructured":"Mitsui J., Hori Y., Tanaka M.\u2013Thermohydrodynamic analysis of cooling effect of supply oil in circular journal bearings.
