...Indrasis Mitra; Indranil Ghosh The effect of surface roughness on the thermohydraulics in minichannels has been studied numerically. Fluid flow (at low Reynolds number) through a typical three-dimensional (3D) channel subjected to constant heat flux (at the bottom) is analyzed incorporating surface...

.... The study is aimed at providing quantitative information on the sources for such discrepancies. heat transfer coefficient microtube heat loss axial heat conduction viscous heating minichannel Experiments were conducted to investigate local heat transfer coefficients and flow...

..., this paper investigates experimentally the potential for enhancing single-phase convection cooling rates by applying pulsating flow. To this end, a pulsator device is developed which allows independent continuous control of pulsation amplitude and frequency. For a single minichannel geometry (1.9 mm...

...E. Da Riva; D. Del Col A three-dimensional volume of fluid (VOF) simulation of condensation of R134a inside a 1 mm i.d. minichannel is presented. The minichannel is horizontally oriented and the effect of gravity is taken into account. Simulations have been run both with and without taking...

... water two-phase microchannel minichannel channel diameter Gas–liquid flows have been studied extensively due to their presence in nature and usefulness in many important industrial applications including oil transport, steam generation, and cooling systems for the production of energy...

...Alberto Cavallini; Davide Del Col; Marko Matkovic; Luisa Rossetto Condensation in minichannels is widely used in air-cooled condensers for the automotive and air-conditioning industry, heat pipes, and compact heat exchangers. The knowledge of pressure drops in such small channels is important...
