1
Life in Moving Fluids: The Physical Biology of Flow
Pressure drag is also a result of viscosity, but a less direct one. It occurs mainly
because of separation and the consequent fact that the dynamic pressure on the
front is not counterbalanced by an equal and opposite pressure on the rear.

Pressure drag and skin friction drag The total action that a fluid exerts on a body
can be considered as the resultant of the elementary forces exerted on all points
of the surface, both normally and tangen- tially. Considering the drag on a closed
...

Mechanics of Fluids, Seventh Edition
This force is known as the pressure drag or. since it depends on the form (i.e. the
shape) of the boundary, the form drag. Thus, whereas the skin friction drag is the
resultant of the forces tangential to the surface, the pressure drag is the resultant
...

Air and Water: The Biology and Physics of Life's Media
4.4 Fluid-Dynamic Forces There are four major hydrodynamic forces, and three of
these, pressure drag, lift, and acceleration reaction, are directly proportional to
the density of the medium. The fourth, friction drag, will be discussed in chapter 5.

Understanding Aerodynamics: Arguing from the Real Physics
The pressure-drag term is fundamentally different and cannot be properly seen
as a local drag contribution. There are reasons for this on two levels: 1. The local
pressure-drag term depends on the overall pressure level in the environment, ...

High Perf Singl Phas Ht Exch Pb
The pressure drag coefficient cw of cylindrical bodies at moderate and high Re is
due to pressure forces. The variation in the total drag coefficient of a circular and
elliptical cylinder in turbulent infinite flow is shown in Fig. 10. 15 on the basis of ...

The Aerodynamics of Heavy Vehicles: Trucks, Buses, and Trains
The aerodynamic drag can be divided into two components: viscous drag and
pressure drag. For the flow over a heavy vehicle at highway speeds, the
Reynolds number is large enough such that viscous forces can be safely ignored.

A Guide to Bycatch Reduction in Tropical Shrimp-trawl Fisheries
As a trawl is towed along two types of drag are present, pressure drag and friction
drag. Pressure drag is caused by variation in water pressure acting on the trawl,
and is the result of forced displacement of water through and around the ...

The type of flow around an object in a fluid dictates the second contribution to
drag, pressure drag or form drag, sometimes called inertial drag since a quantity
of fluid has to be moved out of the way for the object to pass through the fluid.
