Application of volume of fluid (VOF) method in conjunction with shear stress transport (SST) k-ω turbulence closure model to investigate spillway flow
Bayrakdar, Fatih; Tokyay Sinha, Talia Ekin; Department of Civil Engineering (2017)
Hydraulic engineers often require to assess the reasons and consequences of interaction of flow with structures. Computational Fluid Dynamics (CFD) became a useful tool in this regard in recent years as it provides ample amount of information both on flow and its interaction with its surrounding. To this end, flows over a spillway are investigated. The computational domain for the flow over a spillway is based on the study by Dargahi (2006). Numerical results are compared to previous experimental ones. In t...
Direct numerical simulation of liquid flow in a horizontal microchannel
Kükrer, Cenk Evren; Tarı, İlker; Department of Mechanical Engineering (2005)
Numerical simulations of liquid flow in a micro-channel between two horizontal plates are performed. The channel is infinite in streamwise and spanwise directions and its height is taken as m, which falls within the dimension ranges of microchannels. The Navier-Stokes equations with the addition of Brinkman number (Br) to the energy equation are used as the governing equations and spectral methods based approach is applied to obtain the required accuracy to handle liquid flow in the microchannel. It is know...
Liquid crystal-templated synthesis of polymeric microparticles with complex nanostructures
Akdeniz, Burak; Büküşoğlu, Emre; Department of Chemical Engineering (2019)
Liquid crystals (LC), when combined with photolithography, enable synthesis of microparticles with two- and three-dimensional shapes and internal complexities. We prepared films of nematic LCs using mixtures of reactive (RM257) and non-reactive mesogens (E7) with controlled alignment of LCs at the confining surfaces, photopolymerized the RM257 using a photomask, and then extracted the unreacted mesogens to yield polymeric microparticles. The extraction resulted in a controlled anisotropic shrinkage with an ...
Investigation of a generic warhead containing plastic bonded explosive under liquid fuel fire by numerical and test methods
Şahin, Hakan; Kurtuluş, Dilek Funda; Narin, Bekir; Department of Aerospace Engineering (2015)
The present work provides a design methodology for a munition against fast cook-off threat for type V insensitivity requirement. The experimental and numerical results for a generic test item (warhead) filled with a PBXN-109 explosive are presented. Two key points for the design of an insensitive munition against fast cook-off threat, which are time to reaction and critical vent area is studied. Dividing the problem as pre-ignition and post- ignition will allow one to manage this complex problem to handle e...
