Effect of Wall Shear Stress Distribution on Manning Coefficient of Smooth Open Rectangular Channel Flows
Open channel flow Manning friction coecient Wall shear stress
2009/10/12
The determination of velocity distribution in open channel flows is crucial in many critical engineering problems such as channel design, calculation of energy losses and sedimentation. In this study,...
Nusselt Number and Convection Heat Transfer Coefficient for a Coaxial Heat Exchanger Using Al2O3-Water pH=5 Nanofluid
experimental nanofluid Nusselt number
2010/8/18
Recently, a new class of fluid made up of metal nano-particles in suspension in a liquid, called nanofluid, appeared. Some numerical studies have shown that these new fluids have a higher heat transfe...
OPTIMIZATION OF DESIGN SEISMIC COEFFICIENT BASED ON TOTAL EXPECTED COST FOR GRAVITY TYPE QUAY WALLS
quay wall seismic coefficient seismic risk risk management
2008/12/30
An optimization procedure for the design seismic coefficient for gravity type quay walls is discussed based on the risk management concept. First, seismic risk evaluation for 280 ports in Japan is co...
