In the past several years, an increasing number of energy-saving strategies have been proposed, and end-users have pushed industries and researchers to concentrate on improving the pump efficiency to save energy. In the early research, developing excellent hydraulic model as the most common way to improve the pump efficiency. Now the pump efficiency has reached a relatively high condition.&nbsp;Energy loss in the pump depends on Reynolds number and relative surface roughness, so the pump efficiency is obviously affected by some parameters such as pump size, fluid speed, fluid viscosity and surface roughness. As a result, the surface roughness plays a more and more important role in improving the pump efficiency. The aim of the present research is a in-depth study, overlaying multiple perspectives,on the relationships between the surface roughness and the pump performance.<\/span><\/p>\r\n<p style=\"text-align: justify\"><span style=\"color: #000000\">The effects of pump-surface-roughness on performance and cavitation will be evaluated by systematic experimental and numerical analyses. Turning, milling and painting processes will be considered and compared in terms of cost and benefit.<\/span><\/p>\r\n\r\n<h2 style=\"text-align: center\"><span style=\"color: #000000\">Tools<\/span><\/h2>\r\n<p style=\"text-align: left\"><span style=\"color: #000000\"><strong>Facility<\/strong> \u2013 <span style=\"color: #0000ff\"><a style=\"color: #0000ff\" href=\"https:\/\/research.dii.unipd.it\/tes\/facilities\/pump-facility\">Pump Facility<\/a><\/span><\/span><\/p>\r\n<p style=\"text-align: left\"><span style=\"color: #000000\"><strong>Mesh Tools<\/strong> \u2013 <span style=\"color: #0000ff\"><a style=\"color: #0000ff\" href=\"https:\/\/www.ansys.com\" class=\"\">ICEM<\/a><\/span><\/span><\/p>\r\n<p style=\"text-align: left\"><span style=\"color: #000000\"><strong>CFD Tools<\/strong> \u2013 <span style=\"color: #0000ff\"><a style=\"color: #0000ff\" href=\"https:\/\/www.ansys.com\" class=\"\">ANSYS CFX<\/a><\/span><\/span><\/p>\r\n<p style=\"text-align: left\"><span style=\"color: #000000\"><strong>Post Processing Tools<\/strong> \u2013 <span style=\"color: #0000ff\"><a style=\"color: #0000ff\" href=\"https:\/\/www.ansys.com\" class=\"\">ANSYS<\/a><\/span><\/span><\/p>\r\n\r\n<h2 style=\"text-align: center\"><span style=\"color: #000000\">Publications<\/span><\/h2>\r\n<h2 style=\"text-align: center\"><span style=\"color: #000000\">Contacts<\/span><\/h2>\r\n<div class=\"WordSection1\">\r\n<div id=\"page-content\" class=\"page-content\">\r\n<div class=\"content\">\r\n<div id=\"team-2\" class=\"team-2 content-section content-section-spacing\" style=\"background-image: none\" data-label=\"Team\" data-id=\"team-2\" data-export-id=\"team-2\" data-category=\"team\">\r\n<div class=\"gridContainer\">\r\n<div class=\"row spaced-cols content-center-sm center-sm\" data-type=\"row\">\r\n<div class=\"col-sm-4 col-md-4 \">\r\n<div class=\"card y-move no-padding bordered\">\r\n<div class=\"col-padding-small col-padding-small-xs description-container\" data-type=\"column\">\r\n<p class=\"\"><b><span style=\"font-size: 12.0pt;color: #212121\"><img decoding=\"async\" loading=\"lazy\" class=\"size-full wp-image-717 aligncenter\" src=\"https:\/\/research.dii.unipd.it\/tes\/wp-content\/uploads\/sites\/15\/2020\/06\/Giorgio.png\" alt=\"Prof. Giorgio Pavesi\" width=\"234\" height=\"300\"><\/span><\/b><\/p>\r\n<p class=\"\" align=\"center\"><span style=\"color: #000000\"><strong>Prof. Giorgio Pavesi<\/strong><\/span><\/p>\r\n<p class=\"\" align=\"center\"><span style=\"color: #000000\"><strong>Head of the TES Laboratories<\/strong><\/span><\/p>\r\n<p class=\"\" align=\"center\"><a href=\"mailto:giorgio.pavesi@unipd.it\">giorgio.pavesi@unipd.it<\/a><\/p>\r\n<p class=\"\" align=\"center\"><span style=\"color: #000000\">+39-049-827-6768<\/span><\/p>\r\n<p class=\"\" align=\"center\"><span style=\"color: #00ccff\"><a style=\"color: #00ccff\" href=\"https:\/\/orcid.org\/0000-0002-2315-4358\" target=\"_blank\" rel=\"noopener noreferrer\" class=\"\">ORCID page<\/a><\/span><\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<div class=\"col-sm-4 col-md-4 \">\r\n<div class=\"card y-move no-padding bordered\">\r\n<div class=\"col-padding-small col-padding-small-xs description-container\" data-type=\"column\">\r\n<p class=\"\"><b><span style=\"font-size: 12.0pt;color: #212121\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone wp-image-2102 size-medium\" src=\"https:\/\/research.dii.unipd.it\/tes\/wp-content\/uploads\/sites\/15\/2022\/05\/Deng-Qifan-233x300.jpg\" alt=\"\" width=\"233\" height=\"300\"><\/span><\/b><\/p>\r\n<p class=\"\"><b><span style=\"font-size: 12.0pt;color: #212121\"><\/span><\/b><span style=\"color: #000000\"><strong>Deng Qifan<\/strong><\/span><\/p>\r\n<p class=\"\" align=\"center\"><a href=\"mailto:qifan.deng@studenti.unipd.it\"> qifan.deng@studenti.unipd.it<\/a><\/p>\r\n<p class=\"\" align=\"center\"><span style=\"color: #000000\">+39-049-827-6700<\/span><\/p>\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Research activities Experimental test on Pumps with different roughness Turning, milling and painting effects on pumps characteristics Projects According to statistics, the energy consumption of pumps accounts for nearly 22% of the world\u2019s energy used by electric motors; thus, pumps have huge energy consumption and considerable energy-saving potential.
