A Computational Framework For Aerodynamic And Aeroelastic Modeling Of Wind Loads On Tall Buildings, Abiy Fantaye Melaku
A Computational Framework For Aerodynamic And Aeroelastic Modeling Of Wind Loads On Tall Buildings, Abiy Fantaye Melaku
Electronic Thesis and Dissertation Repository
Driven by the burgeoning growth of computing power over the last few decades, the capability of computational fluid dynamics (CFD) to simulate turbulent flows of practical interest has progressed rapidly. In the past, a notable research effort has been dedicated to applying CFD for modeling wind loads on structures, particularly for tall buildings. However, the current state of CFD for wind load evaluation of tall buildings using Large-Eddy Simulation (LES) has several critical challenges, including the treatment of atmospheric boundary layer (ABL) flow conditions, turbulence modeling of separated flows around buildings, and simulation of wind-structure interaction for dynamically sensitive buildings. …
A Model For Complex Heat And Mass Transport Involving Porous Media With Related Applications, Furqan A. Khan
A Model For Complex Heat And Mass Transport Involving Porous Media With Related Applications, Furqan A. Khan
Electronic Thesis and Dissertation Repository
Heat and mass transfer involving porous media is prevalent in, for example, air-conditioning, drying, food storage, and chemical processing. Such applications require non-equilibrium heat and mass (or moisture) transfer modeling inside porous media in conjugate fluid/porous/solid framework. Moreover, modeling of turbulence and turbulent heat and mass transfer becomes essential for many applications. A comprehensive literature review shows a scarcity of models having such capabilities. In this respect, the objectives of the present thesis are to: i) develop a formulation that simulates non-equilibrium heat and mass transfer in conjugate fluid/porous/solid framework, ii) demonstrate the capabilities of the developed formulation by simulating …
