The response to steady-state and oscillatory strain rates of lean, premixed hydrocarbon-air flames with and without H2 doping has been investigated analytically, numerically and experimentally. The analytical analysis provides a theoretical framework for assessing steady-state flame temperature (Tflame) response to ...

In this dissertation, an optical sensor for combustion diagnostics, based on near-infrared distributed feedback (DFB) tunable diode lasers, is developed. The sensor is implemented to perform simultaneous species and temperature measurements in a combustion system. The use of optical sensing ...

Uncertainty is inevitable in engineering design optimization and can significantly degrade the performance of an optimized design solution and/or even change feasibility by making a feasible solution infeasible. The problem with uncertainty can be exacerbated in multi-disciplinary optimization whereby the ...

Finite element modal was performed on structure(T-form) with free boundary conditions and an experimental modal was performed on the table in the student lab. FRF coupling was achieved between the updated modal of the structure and the experimental modal of ...

Excitation of a combusting flow near its preferred mode to increase volumetric energy release has been studied for many years on internal systems. Excitation promotes the production and propagation of large scale vortices, which have been shown to improve combustion. ...

In this dissertation a new class of spatial micromechanisms employing compliant joints and electrothermal motors has been developed. The spatial micromechanisms contain three limbs driven by individual electrothermal linear motors to form multiple degree-of-freedom (DOF) manipulators. At the coaxial point ...

The development project has been done in cooperation with Faurecia Exhaust Systems AB in Torsås that constructs and manufactures manifolds, catalytic converters, mufflers and whole exhaust systems.The task with this project was to find a new solution concept for the ...

Polypyrrole/gold bilayers are being developed as micro-actuators for several applications. The goal of this thesis was to use these bilayers in a micro-valve to control female urinary incontinence. Several substrate materials and designs were investigated, with noteworthy findings, including the ...

The need exists to fabricate graded metal-ceramic composites in bulk manufacturing processes for commercial applications. To address this need, a three-fold approach is employed: (1) control of the evolution of shrinkage strain and mechanical properties through the use of a ...

The challenges and benefits of using a liquid-cooled cold plate to cool a multi-processor circuit board with complex geometry were explored. Two cold plates were designed, fabricated, and tested experimentally. Thermal interface resistance was experimentally discovered and confirmed with numerical ...
