Influence of mainstream turbulence and unsteady wake on turbine blade heat transfer
(1993)
The influence of mainstream turbulence and unsteady wake on turbine blade surface heat transfer was studied. The experiments were performed with a five-blade linear cascade in a low speed wind tunnel facility. The wake and ...
Thermodynamic, viscoelastic and rheological structure-property relationships of rigid poly(vinyl chloride)-styrenic copolymer blends
(1994)
In order to extend low temperature properties, rubber modification of PVC is commonly employed. The upper use temperature is however still restricted. To counter this problem modification using higher glass transition ...
System parameter analysis for robot manipulators with position-invariant natural frequencies
(1994)
The flexible PFBL (parallel-four-bar-linkage) link mechanism is designed to increase rigidity and to reduce the position variation of natural frequencies. The position variation of natural frequencies is the change of ...
Boiling in small diameter tubes
(1973)
Boiling in small cross section channels has not received as much attention as in large cross section channels. It is noted in the literature that higher heat transfer coefficients can be expected in the small cross section ...
An investigation of the impact behavior of a rigid body
(1967)
Modern freeways require adequate lighting facilities, and in order to meet lighting requirements, light posts sometimes have to be located near the edge of the traffic lane. Single post sign standards and stop light posts ...
An investigation of the nature of microstructural damage in a filled elastomeric compostie material
(1968)
Elastomeric composite materials have been of interest for some time. With the advent of solid rocket propellants, however, a critical need has developed for the evaluation of those mechanical properties needed for structural ...
An experimental investigation of boiling burnout for subcooled carbon tetrachloride under conditions of constrained vapor space volume
(1968)
It has been determined that boiling heat flux densities may be made to exceed maximum pool boiling values for the same pressure and subcooling. Heat flux density elevations of about 50% were measured, and larger values may ...
Robot path planning in the presence of stationary and moving obstacles
(1987)
Planning the path of a manipulator through an obstacle strewn workspace is a problem that must be solved if completely autonomous robotic manipulators are to safely operate. Many solutions to the problem have been posed ...
Planar diffuser performance improvement using injection along the straight diverging walls at subsonic to transonic Mach numbers
(1986)
Planar diffusers with injection along the diverging walls were investigated relative to their pressure recovery performance. Injection orientation, location and slot width were varied for diffusers with aspect ratios of ...
Effect of backfill on the performance of a vertical U-tube ground coupled heat pump
(1995)
The present work is concerned with developing a discretized analytical model to investigate the effect of a backfill on the performance of a vertical U-tube ground-coupled heat pump. This work involves the development of ...
