Resumo: | In this work, the application of protrusions and nanofluids to improve the performance of tubular-microchannel heat sink (MCHS) is proposed and investigated computationally. The three-dimensional Navier-Stokes and energy equations were solved numerically using the finite volume method incorporated into the ANSYS (Fluent) software package. The effects of different types of nanofluid (Al2O3, CuO, ZnO in pure water), the volume fraction of the nanoparticles (0% to 4%) and height of the protrusion ( 2um-6um) on microchannel heat sinks were investigated under the steady-state condition and Reynold numbers (400-2000) with constant heat flux of 9 x 106 W/m2. It was revealed that thermal performance improved as protrusion height increased. At Re=2 000 , for Al2O3 nanofluid (NAN) with a volume fraction ( of 4% and a protrusion height (H) of 2um to 6um yielded a thermal performance value of 1.59, 1.68, 1.77, 1.86, and 1.96 times that of MCHS without the protrusion, respectively. In addition, at a volume fraction of 4%, protrusion height of 6um and Reynolds number of 800, the Al2O3, CuO, and ZnO nanofluids yielded a thermal performance value of 1.79, 1.08, and 1.07 times that of pure water, respectively. Furthermore, at a Reynolds number of 400 and a volume fraction of 4%, the Al2O3–water nanofluid reduced the maximum temperature of the MCHS wall by 4% , whereas - and -nanofluids decreased the MCHS wall maximum temperature by 0.5% and 0.48% when compared to pure water, respectively. However, for all the cases of volume fraction (1% to 4%), there was an increase trend in the value of thermal performance for the Reynolds number range of 400 to 800 , and decrease with the Reynolds number range of 800 to 2 000. |

As equações tridimensionais de Navier-Stokes e energia foram resolvidas numericamente usando o método de volume finito incorporado ao pacote de software ANSYS (Fluent). Os efeitos de diferentes tipos de nanofluido (Al2O3, CuO, ZnO em água pura), a fração de volume das nanopartículas (0% a 4%) e a altura da saliência ( 2um-6um) em dissipadores de calor microcanal foram investigados sob a condição de estado estável e números de Reynold (400-2000) com fluxo de calor constante de 9 x 106 W/m2. Foi revelado que o desempenho térmico melhorou à medida que a altura da saliência aumentava. Foi revelado que o desempenho térmico melhorou à medida que a altura da saliência aumentava. Em Re=2 000 , para Nanofluida Al2O3 (NAN) com uma fração de volume ( de 4% e uma altura de saliência (H) de 2um a 6um rendeu um valor de desempenho térmico de 1,59, 1,68, 1,77, 1,86 e 1,96 vezes o de MCHS sem as prolagens, respectivamente. Além disso, com uma fração de volume de 4%, altura de saliência de 6um e reynolds número de 800, os nanofluidos Al2O3, CuO e ZnO produziram um valor de desempenho térmico de 1,79, 1,08 e 1,07 vezes o de água pura, respectivamente. Além disso, com um número reynolds de 400 e uma fração de volume de 4%, o nanofluido al2O3-água reduziu a temperatura máxima da parede mchs em 4%, enquanto - e -nanofluidas reduziram a temperatura máxima da parede mchs em 0,5% e 0,48% quando comparada à água pura, respectivamente. No entanto, para todos os casos de fração de volume (1% a 4%), houve um aumento no valor do desempenho térmico para a faixa de número reynolds de 400 a 800 , e diminuição com a faixa de número reynolds de 800 a 2 000.Universidade Federal de Viçosa - UFV2022-04-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo, Manuscrito, Eventosapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1423310.18540/jcecvl8iss5pp14233-01eThe Journal of Engineering and Exact Sciences; Vol. 8 No. 5 (2022); 14233-01eThe Journal of Engineering and Exact Sciences; Vol. 8 Núm. 5 (2022); 14233-01eThe Journal of Engineering and Exact Sciences; v. 8 n. 5 (2022); 14233-01e2527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVenghttps://periodicos.ufv.br/jcec/article/view/14233/7311Copyright (c) 2022 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFetuga, Ibrahim AdemolaOlakoyejo, Olabode ThomasSiqueira, Antônio Marcos de OliveiraGbegudu, Joshua KolawoleAdeyemi, Ebenezer Aderibigbe2022-08-11T17:47:50Zoai:ojs.periodicos.ufv.br:article/14233Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2022-08-11T17:47:50Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false |
