Análise experimental da ebulição em canais de diâmetro reduzido: efeitos do diâmetro, do fluido e da temperatura
(Universidade do Vale do Rio dos Sinos, 2018-05-11)
The use of heat exchangers with reduced diameter channels has been growing due to the demand for compact heat exchangers which allow high rates of heat transfer, low pressure drop and reduction of refrigerant fluid charge ...
VEGETABLE OIL STRUCTURE AND ANTIOXIDANTS
(UNIV ZAGREB FAC MECHANICAL ENGINEERING & NAVAL ARCHITECTURE, 2010)
Five vegetable oils: canola, soybean, corn, cottonseed and sunflower oils were characterized with respect to their composition by gas chromatography and viscosity. The compositions of the vegetable oils suggest that they ...
Influência da interação fluido-superfície sobre a dinâmica de nucleação de bolhas de vapor em cavidades artificiais
(Universidade Estadual Paulista (Unesp), 2021-08-06)
A constante procura por técnicas que otimizem o processo de transferência de calor, incluindo mudança de fase, torna necessária a compreensão da dinâmica da bolha de vapor no processo de ebulição. Dessa forma, o presente ...
