Numerical Study of Water/Al2O3 Nanofluid Forced Convection in a Rotating Hydrophilic and Hydrophobic Microchannel

Autor: A. Sohankar, M. Riahi, E. Shirani

Publikováno v: Journal of Applied Fluid Mechanics, Vol 12, Iss 1, Pp 219-231 (2019)

In this work, water and water/Al2O3 nanofluid forced convection are studied numerically through a rotating U-shaped microchannel. The hydrophilic (no-slip flow) and hydrophobic (with slip length of 5 μm) conditions are used on the microchannel walls

Autor: M. R. Rastan, A. Sohankar

Publikováno v: Ravish/hā-yi ̒adadī dar Muhandisī, Vol 36, Iss 2, Pp 1-20 (2018)

In the first part of the present study, a two dimensional half-corrugated channel flow is simulated at Reynolds number of 104, in no-slip condition (hydrophilic surfaces( using various low Reynolds turbulence models as well as standard k-ε model; an

Onset of Vortex Shedding and Hysteresis in Flow over Tandem Sharp-Edged Cylinders of Diverse Cross Sections

Autor: Kouchakzad, M., Sohankar, A., Rastan, M. R.

Numerical simulations are conducted to analyze flow characteristics around two tandem sharp-edged cylinders with cross sections of square (b*1 = 1) for the upstream cylinder and rectangle (b*2) for the downstream cylinder (b* = b/a, where a and b are

Evaluating the safety and aesthetic of a city park (Case study: Saee Park in Tehran)

Autor: Zeinab Sohankar

Publikováno v: Entorno Geografico, Iss 28 (2024)

Proximity to green spaces, waterside, and various cultural or recreational objects increase the quality of life. Nevertheless, the neighborhood with the urban park also has adverse effects on the quality of life. The purpose of this research is to in
