Investigations are performed for Reynolds number Re less than 200, power-law index n ranging from 0.5 to 1.5 and consistency index K varying from 0.001 to 0.5 to explore heat transfer and flow structure of shear-thinning fluid and shear-thickening fluid. Results indicate that with the increase of n, K for a given Re, wall Nusselt number increases mainly attributing to the increase of inlet velocity U. For a given inlet velocity, wall Nusselt number decreases with the increase of n and K, which mainly attributes to the increase of apparent viscosity and the reduction of momentum diffusion. For the same Re, U and Pr, wall Nusselt number decreases with the increase of n. Among the study of industrial power-law shear-thinning fluid, CMC solution with 100 ppm shows the best heat transfer performance at a given velocity. Moreover, new correlation of Nusselt number about industrial fluid is proposed. In general, for the heat transfer of laminar confined impinging jet, it is best to use the working fluid with low viscosity.<\/jats:p>","DOI":"10.3390\/e20100800","type":"journal-article","created":{"date-parts":[[2018,10,18]],"date-time":"2018-10-18T10:55:41Z","timestamp":1539860141000},"page":"800","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Heat Transfer and Flow Structures of Laminar Confined Slot Impingement Jet with Power-Law Non-Newtonian Fluid"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4790-9046","authenticated-orcid":false,"given":"Yan","family":"Qiang","sequence":"first","affiliation":[{"name":"College of Energy and Power Engineering, Lanzhou University of Technology, Lanzhou 730050, China"},{"name":"Key Laboratory of Fluid Machinery and System, Lanzhou 730050, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liejiang","family":"Wei","sequence":"additional","affiliation":[{"name":"College of Energy and Power Engineering, Lanzhou University of Technology, Lanzhou 730050, China"},{"name":"Key Laboratory of Fluid Machinery and System, Lanzhou 730050, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaomei","family":"Luo","sequence":"additional","affiliation":[{"name":"China North Vehicle Research Institute, Beijing 100071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongchao","family":"Jian","sequence":"additional","affiliation":[{"name":"College of Energy and Power Engineering, Lanzhou University of Technology, Lanzhou 730050, China"},{"name":"Key Laboratory of Fluid Machinery and System, Lanzhou 730050, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenan","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Energy and Power Engineering, Lanzhou University of Technology, Lanzhou 730050, China"},{"name":"Key Laboratory of Fluid Machinery and System, Lanzhou 730050, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fenfen","family":"Li","sequence":"additional","affiliation":[{"name":"College of Energy and Power Engineering, Lanzhou University of Technology, Lanzhou 730050, China"},{"name":"Key Laboratory of Fluid Machinery and System, Lanzhou 730050, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,10,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.expthermflusci.2006.12.006","article-title":"An experimental investigation of free and submerged miniature liquid jet array impingement heat transfer","volume":"32","author":"Robinson","year":"2007","journal-title":"Exp.
