A basic model of hydrogen circulation in a proton exchange membrane (PEM) fuel cell
(Texas Tech University, 1999-12)The fuel cell has come a long way since Sir Hubert Davy built the first prototype in 1801. After a slow 150 years, the fuel cell came to the attention of the world with the first slew of fuel cell operated vehicles in the ... -
A computational model to calculate the flow-induced pressure fluctuations on a bluff body
(Texas Tech University, 2002-08)Pressure fluctuations on buildings cause vibrations in moderate winds and structural damage under severe winds. They also play an important role in determining the noise level inside buildings and automobiles. Therefore, ... -
A computational study of coherent structures in the wakes of two-dimensional bluff bodies
(Texas Tech University, 1988-08)The periodic shedding of vortices from bluff bodies was first recognized in the late 1800's. Currently, there is great interest concerning the effect of vortex shedding on structures and on vehicle stability. In the design ... -
A computational study of laminar and turbulent flows in rotating rectangular ducts
(Texas Tech University, 1993-12)Rotating flow problems have long been of interest in fluid mechanics because they have a wide range of applications in engineering practice. The flow of fluid in the radial passageways of radial pumps or centrifugal ... -

A flexible capacitance sensor integrated micropump for precise volume control
(2017-05)Pneumatically actuated micropumps are operated by external pressure sources that enable deflection of the thin PDMS membrane. Depending on the geometrical parameters of the microvalve, these micropumps can deliver microliter ... -
A framework for assessing domain transfer risk in biologically inspired design
(2015-05)Inherent in Biomimetic design is the selection of one or more biological analogues from which one or more strategies are extracted and transferred into the engineering domain. This cross-domain transfer (Biology to ... -
A laser-induced surface flow visualization technique using liquid crystal thermography
(Texas Tech University, 2002-12)Observation of flow field characteristics such as flow separation and reattachment are important in many industries. Current methods for flow visualization can be difficult to implement, expensive, and highly intrusive. ... -
