Journal ArticleDOI
Dynamic stall simulation of a pitching airfoil under unsteady freestream velocity
Kobra Gharali,David A. Johnson +1 more
TL;DR: In this paper, the effects of horizontal oscillations of the freestream velocity superimposed on a pitch oscillating NACA0012 airfoil were investigated using Computational Fluid Dynamics (CFD).
Journal ArticleDOI
A comprehensive study of geothermal heating and cooling systems
Madjid Soltani,Farshad Moradi Kashkooli,Alireza Dehghani-Sanij,Alireza Kazemi,N. Bordbar,M. J. Farshchi,M. Elmi,Kobra Gharali,Maurice B. Dusseault +8 more
TL;DR: Geothermal heat is an energy source that is local, reliable, resilient, environmentally-friendly, and sustainable as mentioned in this paper, and has different applications, such as heating and cooling of buildings, generating electricity, providing warm/cold water for agricultural products in greenhouses, and balneological use.
Journal ArticleDOI
Environmental, economic, and social impacts of geothermal energy systems
Madjid Soltani,Farshad Moradi Kashkooli,Farshad Moradi Kashkooli,Mohammad Kazem Souri,Behnam Rafiei,Mohammad Jabarifar,Kobra Gharali,Kobra Gharali,Jatin Nathwani +8 more
TL;DR: In this paper, the authors provide a detailed review of the barriers, identify credible solutions and highlight options for enhancing geothermal capacity and energy production on a global scale required to meet ‘net-zero’ carbon emission targets.
Journal ArticleDOI
Numerical modeling of an S809 airfoil under dynamic stall, erosion and high reduced frequencies
Kobra Gharali,David A. Johnson +1 more
TL;DR: In this article, an oscillating freestream over a stationary S809 airfoil is simulated numerically using ANSYS Fluent 12.1 and compared with aerodynamic coefficients from existing experimental and semi-empirical data.
Journal ArticleDOI
Design, thermodynamic, and wind assessments of a compressed air energy storage (CAES) integrated with two adjacent wind farms: A case study at Abhar and Kahak sites, Iran
Amir Reza Razmi,Amir Reza Razmi,Madjid Soltani,Armin Ardehali,Kobra Gharali,Kobra Gharali,Maurice B. Dusseault,Jatin Nathwani +7 more
TL;DR: In this paper, the authors proposed a Compressed Air Energy Storage (CAES) facility for two adjacent wind farms, Abhar and Kahak sites in Iran, with a total nominal power of 162.5MW.
