The flow along the walls, characterized by a non-uniform temperature, is under the effect of the uniform magnetic field acting transversely to the flow direction. The walls of the channel are permeable. The flow is due to convection combined with uniform suction\/injection at the boundary. The model is formulated in terms of unsteady, one-dimensional partial differential equations (PDEs) with imposed physical conditions. The cluster effect of nanoparticles is demonstrated in the      C 2   H 6   O 2     , and      H 2  O     base fluids. The perturbation technique is used to obtain a closed-form solution for the velocity and temperature distributions. Based on numerical experiments, it is concluded that both the velocity and temperature profiles are significantly affected by    \u03d5   . Moreover, the magnetic parameter retards the nanofluid motion whereas porosity accelerates it. Each      H 2  O    -based and      C 2   H 6   O 2     -based nanofluid in the suction case have a higher magnitude of velocity as compared to the injections case.<\/jats:p>","DOI":"10.3390\/sym11030378","type":"journal-article","created":{"date-parts":[[2019,3,15]],"date-time":"2019-03-15T04:12:09Z","timestamp":1552623129000},"page":"378","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["MHD Nanofluids in a Permeable Channel with Porosity"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2056-9371","authenticated-orcid":false,"given":"Ilyas","family":"Khan","sequence":"first","affiliation":[{"name":"Faculty of Mathematics and Statistics, Ton Duc Thang University, Ho Chi Minh 72915, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0911-3346","authenticated-orcid":false,"given":"Aisha M.","family":"Alqahtani","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Princess Nourah bint Abdulrahman University, Riyadh 11564, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"312","DOI":"10.1002\/sapm1953321312","article-title":"Boundary Layer Control by Distributed Surface Suction or Injection.
