Numerical simulation and analytical optimization of microchannel heat sinks
Türkakar, Göker; Okutucu Özyurt, Hanife Tuba; Department of Mechanical Engineering (2010)
This study has two main objectives: The performance evaluation of existing microchannel heat sinks using a CFD model, and the dimensional optimization of various heat sinks by minimizing the total thermal resistance. For the analyses, the geometric modeling is performed using the software GAMBIT while the thermal analysis is performed with FLUENT. The developed model compares very well with those available in the literature. Eight different metal-polymer microchannel heat sinks are analyzed using the model ...
Numerical simulation of non-energetic reactive armors
Kurt, Mert Can; Gürses, Ercan; Department of Aerospace Engineering (2017)
Non-energetic reactive armors (NERAs) are one type of reactive armors which are developed to reinforce main armors of heavily armoured vehicles. Non-energetic reactive armors also called as bulging armors are known to be effective against lethal effects of shaped charges. Their structures are like sandwich structures and consist of one intermediate layer between two outer metal plates. The intermediate layer is made of inert materials such as rubber or polymers. The intermediate layer and the outer metal pl...
Numerical simulation of turbine internal cooling and conjugate heat transfer problems with Rans based turbulance models
Görgülü, İlhan; Akmandor, İbrahim Sinan; Department of Aerospace Engineering (2012)
The present study considers the numerical simulation of the different flow characteristics involved in the conjugate heat transfer analysis of an internally cooled gas turbine blade. Conjugate simulations require full coupling of convective heat transfer in fluid regions to the heat diffusion in solid regions. Therefore, accurate prediction of heat transfer quantities on both external and internal surfaces has the uppermost importance and highly connected with the performance of the employed turbulence mode...
Numerical Validation of a Pyroshock Test System and Application to Qualification Tests
Yalçınkaya, Tuncay; Gursoy, Bahadir (2022-08-01)
Spacecraft are exposed to severe mechanical loads, i.e., shock loads, during their journey to orbit. Such loads usually develop due to a separation event through the activation of pyrotechnic devices. They might be transmitted throughout the entire structure and strongly influence the service performance of electronic components. Therefore, it is crucial to study whether the instruments can resist such a harsh environment. However, due to the vulnerability and high cost of the equipment, experimental setups...
Numerical investigation of free surface and pipe flow problems by smoothed particle hydrodynamics
Dinçer, Ali Ersin; Bozkuş, Zafer; Department of Civil Engineering (2017)
In the present study, a two-dimensional (2D) computer code for free surface and pipe flows is developed by using Smoothed Particle Hydrodynamics (SPH) approach. For free surface flow problem, idealized dam break problems are investigated numerically. The results of three recently published experimental studies are used to validate the numerical solutions. In addition to mesh-free particle method, SPH with a novel boundary treatment model proposed in the present study, mesh-based methods with turbulence and ...
