Investigation on Non-Steady State-Combustion : 2nd Report, On Pressure Mode Oscillations

Steady State and Transient Oscillations in NH, Oxidation on Ptl

Sustained oscillations of catalyst temperature have been observed in NH, oxidation on Pt wires and foils in a l-atm flow reactor. Simple and complex oscillations with periods from ~1 set to several minutes were obtained for gas compositions between 20 and 40% NH3 in air. These depend sensitively on gas composition, flow velocity, and geometry. Oscillatory behavior is quite stable over short tim...

Investigation On Effects of Contact Area Geometry On Non-Equilibrium System Steady State

In contrast to equilibrium systems, seeking a statistical mechanics description and a corresponding thermodynamics picture for non-equilibrium system is still an unresolved issue. Many experiments, both practical and simulative, have been carried out to investigate its properties. Yet, a general framework to describe non-equilibrium system is still far from obtainable. In this project, numerica...

Investigation on Doubly Fed Induction Generator Steady State Parameters

In this paper steady state characteristic of a variable speed Doubly fed induction generator (DFIG) is investigated. Torque and speed is used as design parameters for DFIG. From mathematical model it is found that on increase of rotor injection voltage and resistance, the torque speed response is shifted from over synchronous to sub synchronous range. The stability of DFIG operation is entirely...

2nd Annual Report on Strees

Influence of increased abdominal pressure on steady-state cardiac performance.

The effect of steady-state increases in abdominal pressure (Pab) on cardiac performance was studied in seven acutely instrumented swine with pneumoperitoneum (PP). The animal was placed on volume-preset ventilation, and PP was created by air insufflation. Cardiac output (CO), right atrial (Pra), left atrial (Pla), pericardial (Ppe), and abdominal inferior vena cava pressures (Pivc) were measure...
