Autor: Akam Aboubakri, Yigit Akkus, Abdolali K Sadaghiani, Khellil Sefiane, Ali Koşar

Publikováno v: Chemical Engineering Journal Advances, Vol 10, Iss , Pp 100255- (2022)

Although droplet evaporation has been studied extensively, the focus is mostly limited to single spherical drops rather than elongated or multiple droplets, which is extensively encountered in a wide range of applications. The present study provides,

Effect of Surface Biphilicity on FC-72 Flow Boiling in a Rectangular Minichannel

Autor: Akam Aboubakri, Vahid Ebrahimpour Ahmadi, Suleyman Celik, Abdolali K. Sadaghiani, Khellil Sefiane, Ali Kosar

Publikováno v: Frontiers in Mechanical Engineering, Vol 7 (2021)

Flow boiling is one of the most effective mechanisms in heat transfer thanks to the latent heat of vaporization. Surface modifications such as mixed-wettability have a considerable effect on the boiling heat transfer performance in terms of enhanceme

Effect of Functional Surfaces with Gradient Mixed Wettability on Flow Boiling in a High Aspect Ratio Microchannel

Autor: Vahid Ebrahimpour Ahmadi, Akam Aboubakri, Abdolali Khalili Sadaghiani, Khellil Sefiane, Ali Koşar

Publikováno v: Fluids, Vol 5, Iss 4, p 239 (2020)

Flow boiling is one of the most effective phase-change heat transfer mechanisms and is strongly dependent on surface properties. The surface wettability is a crucial parameter, which has a considerable effect on the heat transfer performance, particu

Modeling of a Passive-Valve Piezoelectric Micro-Pump: A Parametric Study

Autor: Akam Aboubakri, Vahid Ebrahimpour Ahmadi, Ali Koşar

Publikováno v: Micromachines, Vol 11, Iss 8, p 752 (2020)

Piezoelectric micro-pumps offer many applications and could provide considerable flow rates in miniature systems. This study parametrically investigates the effects of major parameters, namely the length, width and attack angle of valves, piezoelectr
