Understanding Thermal Comfort Impact And Air Movement Around Open Stairs Through The Use Of Cfd Modeling, Ethan Davidson
Understanding Thermal Comfort Impact And Air Movement Around Open Stairs Through The Use Of Cfd Modeling, Ethan Davidson
Graduate Theses and Dissertations
The air exchange between two floors of a building has an impact on thermal comfort. The present research attempts to quantify this impact and identify the contributing factors disrupting the thermal comfort on and around stairs. Various heating and cooling scenarios were analyzed, using CFD modeling, in a simple two-story building separated by a single staircase. The research examines a single building layout with a fixed inlet and outlet configuration. In addition, the study investigated the short-term impact on thermal comfort. As a result, the duration of the simulations varies from two and half minutes to ten minutes, consistent with …

Computational Design Of Nonlinear Stress-Strain Of Isotropic Materials, Askhad M.Polatov, Akhmat M. Ikramov, Daniyarbek Razmukhamedov
Chemical Technology, Control and Management
The article deals with the problems of numerical modeling of nonlinear physical processes of the stress-strain state of structural elements. An elastoplastic medium of a homogeneous solid material is investigated. The results of computational experiments on the study of the process of physically nonlinear deformation of isotropic elements of three-dimensional structures with a system of one- and double-periodic spherical cavities under uniaxial compression are presented. The influence and mutual influence of stress concentrators in the form of spherical cavities, vertically located two cavities and a horizontally located system of two cavities on the deformation of the structure are investigated. Numerical …
Modeling And Tuning Of Cvt Systems For Sae® Baja Vehicles, Sean Sebastian Skinner
Modeling And Tuning Of Cvt Systems For Sae® Baja Vehicles, Sean Sebastian Skinner
Graduate Theses, Dissertations, and Problem Reports
Continuously variable transmission (CVT) describes a family of transmission styles. These systems serve the same purpose as their traditional counterparts; transmitting power while offering a variable gearing ratio. The difference lies in the CVT’s ability to change ratio continuously between a minimum and maximum without halting power transfer. They offer many benefits of an automatic transmission while being significantly lighter. For this reason, CVTs are often used on Baja SAE® vehicles to control gearing ratio.
WVU’s Baja team has used mechanical CVTs for many decades. These systems are simpler in the sense that they don’t require power to operate. …
