Sphere Drag and Heat Transfer
Modelling fluid flows past a body is a general problem in science and engineering. Historical sphere drag and heat transfer data are critically examined. The appropriate drag coefficient is proposed to replace the inertia type definition proposed by Newton. It is found that the appropriate drag coefficient is a desirable dimensionless parameter to describe fluid flow physical behavior so that f...
متن کاملViscometer using drag force measurements.
A robust and precise viscometer using the forces exerted by a laminar flow inside a small duct is presented: the force is measured on a long cylindrical sensor dipped into the flow. Two devices of respective volumes 1.4 and 0.031 ml have been realized, demonstrating that the technique is usable with small fluid volumes. Several Newtonian and non-Newtonian fluids have been tested at shear rates ...

متن کاملDrag force on a sphere moving towards a corrugated wall
From the solution of the creeping-flow equations, the drag force on a sphere becomes infinite when the gap between the sphere and a smooth wall vanishes at constant velocity, so that if the sphere is displaced towards the wall with a constant applied force, contact theoretically may not occur. Physically, the drag is finite for various reasons, one being the particle and wall roughness. Then, f...
متن کاملThe NAL-NL2 Prescription Procedure
After a long gestation period, the NAL-NL2 prescription formula has been derived and is now in the process of being incorporated into software that enables it to be used. Like its predecessor, the NAL-NL2 prescription aims to maximize speech intelligibility whilst keeping overall loudness no greater than that perceived by a normal-hearing person listening to the same sound. The adaptive process...
