One of them is the influence of convective heat exchange on Coand\u00e3 adhesion. This paper presents an even preliminary numerical study of this problem. It analyses the behaviour of a fluid stream on a convex surface in the presence of a temperature gradient between the fluid and the convex surface. It approaches the problem by a set of CFD simulations, analyses previous hypotheses, which are based on Prandtl number, and evidences the need for a model that account Reynolds number. The performed simulations are still not sufficient for an exhaustive comprehension of Coand\u00e3 effect in the presence of heat exchange phenomena. It allows producing some consideration that may help future scientific work in toward a better comprehension of these phenomena. In particular, it verifies the importance of Reynolds number, because it is intrinsic in the adopted model, with good accordance with CFD data. In conclusion, this paper is still far from a complete model of the phenomena that govern the Coand\u00e3 adhesion in the presence of convective heat exchange. Otherwise, it presents a preliminary starting point toward further and more detailed analyses.&lt;\/div&gt;&lt;\/div&gt;<\/jats:p>","DOI":"10.4271\/2020-01-0026","type":"proceedings-article","created":{"date-parts":[[2020,3,10]],"date-time":"2020-03-10T05:01:19Z","timestamp":1583816479000},"source":"Crossref","is-referenced-by-count":0,"title":["Accounting Thermal Exchanges in Coanda Effect"],"prefix":"10.4271","volume":"1","author":[{"given":"Michele","family":"Trancossi","sequence":"first","affiliation":[{"name":"Henri Coanda Labs LLC"}]},{"given":"Jose","family":"Pascoa","sequence":"additional","affiliation":[{"name":"Universidade Da Beira Interior"}]}],"member":"2796","published-online":{"date-parts":[[2020,3,10]]},"reference":[{"key":"ref0","unstructured":"Coanda ,  H. \n \n 1936"},{"key":"ref1","unstructured":"Coanda ,  H. \n \n 1936"},{"key":"ref2","unstructured":"Newman ,  B.G. \n \n The Deflexion of Plane Jets by Adjacent Boundaries -
