Articles in Press, Accepted Manuscript, Available Online from 17 October 2023

  Abstract: In this article, to investigate the severity of damage to the helicopter pilot under the crash impact, the numerical simulation of the real helicopter cockpit seat has been done. To limit the complexity of the problem, a fully vertical impact was considered as a reference scenario for the assembly ...  Read More

Design and optimization of the wing fence of a lambda-shaped aircraft model to reduce the rolling moment coefficient

Mohammad hossein Moghimi Esfandabadi; Mohammad Hassan Djavareshkian

Volume 8, Issue 2 , June 2024, , Pages 13-25

  This research investigates the effect of fence on wingtip vortices and control surfaces in a bird-like aircraft using numerical methods. In designing and placing the fence, average dimensions extracted from wing root vortices at different angles of attack have been used. In addition, the fence with specified ...  Read More

Study of the Effect of Air Suction on Separation Bubble in a Flow Field around a Rectangular Cylinder

Saeed Kavousfar; Amir Rostami

Volume 4, Issue 2 , August 2020, , Pages 34-27

  In this paper, the flow field around a two-dimensional rectangular cylinder was numerically simulated and the effects of the flow suction on the separation bubble were investigated. The purpose was to estimate the effect of suction on the dimensions of the separation bubble. The flow field was assumed ...  Read More

Smooth Particle Hydrodynamics (SPH) Simulation and its Applications in Aerospace

yaser jafari

Volume 1, Issue 2 , December 2017, , Pages 1-15

  Smoothed particle hydrodynamics (SPH) is a relatively new particle and meshfree numerical method which is highly noticed during the last few decades. In comparison to conventional grid-based computational fluid dynamics (CFD) methods, smoothed particle hydrodynamics (SPH) has some unique advantages when ...  Read More
