The equations for the fluid and solid (line heat source) phases are solved simultaneously. The three sides of the computational domain are open boundary. Some of the physical and thermo\u2010physical properties of the fluid (air) such as density, thermal conductivity and viscosity were considered to vary with temperature.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Findings<\/jats:title><jats:p>The present predictions are compared with those using the Boussinesq approximation, with the results for the boundary layer equations, and with the experimental results. The present predictions reveal considerable departure from the Boussinesq\u2010based solution and from the boundary layer results. This study also shows the radiation exchange between the heat source and surrounding has major effect in the results. Thus, the departure between the experimental and analytical results can be explained by the effect of radiation exchange.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Research limitations\/implications<\/jats:title><jats:p>In this work, just studied steady\u2010state laminar thermal plume with the effects of radiation from heat source and the variation of air properties with temperature while it is propose to extend this work to transient and\/or turbulent flow.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Originality\/value<\/jats:title><jats:p>The effect of radiation from a line heat source on the flow filed around the source and offers enhancement of design to thermal engineers.<\/jats:p><\/jats:sec>","DOI":"10.1108\/09615530610636946","type":"journal-article","created":{"date-parts":[[2006,6,30]],"date-time":"2006-06-30T00:59:22Z","timestamp":1151629162000},"page":"28-45","source":"Crossref","is-referenced-by-count":2,"title":["The effect of radiation on the laminar natural convection induced by a line heat source"],"prefix":"10.1108","volume":"16","author":[{"given":"Mohammad B.","family":"Ayani","sequence":"first","affiliation":[]},{"given":"Javad A.","family":"Esfahani","sequence":"additional","affiliation":[]},{"given":"Antonio C.M.","family":"Sousa","sequence":"additional","affiliation":[]}],"member":"140","reference":[{"key":"key2022031420293361700_b16","unstructured":"Anderson, J.D.
