Gradually Varied Granular Flows in a Vertical Chute
Relationship Between Turbulent Structure Near the Free-Surface and Surface-Wave-Fluctuations
An Electrorheological Damper with Annular Duct
Anomalous Measurements in a Compound Duct
An anomalous velocity distribution on the 'flood plain' of a compound duct is reported and discussed. The tentative conclusion is that the phenomenon is to be explained by the co-existence...
Evaluation of Concrete Bridges by Impact-Echo
Strength of post-tensioned bridge structural members primarily depends on the tensile capacity of their post-tensioning steel reinforcement. To prevent corrosion, the post-tensioning steel...
Gas Phase Turbulence Modification with Fine Particles in 2-D Duct Flow
The effect of a dilute suspension of fine particles on a two-dimensional turbulent duct gas flow is measured with hot-film anemometry. The flow field without particles is compared to the...
Progress of Floating Type Wave Power Generator
A floating type wave power generator was improved. It is a Backward Bent Duct Buoy (BBDB) which has an air chamber duct which is bent backwards. It is capable of increasing the peak conversion...
Modeling Sediment Transport in Rectangular Ducts with a Two-Equation Model of Turbulence
The paper deals with the application of a two-equation model of turbulence to the calculation of flows in rectangular ducts. A non-linear relationship is used to link the Reynolds stresses...
Power Without Acid
Anticipating tighter acid rain controls, DOE is developing duct injection units that can be attached to existing powerplants. In a typical duct injection system, lime is sprayed into existing...
The Design of the Outlet for the New Koepchenwerk Pumpstorage Plant
The Koepchenwerk Pumpstorage Plant (1930) is going to be replaced by a new plant with a 150 MW Pumpturbine in a shaft. This paper explains the reasons for this replacement and gives a...

Treating Potential Impact of Components in NPP
Design Verification of HVAC Duct Turning Vanes in Nuclear Power Plants
HVAC ducts in nuclear power plants utilize short radius elbow construction with turning vanes to minimize the space requirement for duct work and to reduce flow losses in the elbows. Turning...
Evaluation of the Ultimate Pressure Capacity of Rectangular HVAC Ducts for Nuclear Power Plants
Structural design criteria are presently based on the AISI Code which limits the duct panel width-to-thickness ratio to a maximum of 500 and the maximum height-to-thickness ratio to 200,...
