A fluid is defined as a substance that deforms continuously under application of a shearing stress, regardless of how small the stress is. Blood is a primary example of a biological fluid. Air can also be considered as biological fluid as it flows in lungs and the synovial fluid between the knee joints is also an example of a biological fluid. Types of Fluids[3] Fluids can be classified into four basic types. They are:
- Ideal Fluid
- Real Fluid
- Newtonian Fluid
- Non-Newtonian fluid
An Ideal Fluid is a fluid that has no viscosity, means it will offer
no resistance, pragmatically this type of fluid does not exist. It is
incompressible in nature. Real fluids are compressible in nature. They
offer some resistance and thus have viscosity. All Fluids existing are
real fluids.
A Newtonian Fluid is a fluid whose viscous shear stresses (acting
between different layers of fluid and between the fluid layer and
surface over which it is flowing) are directly proportional to the rate
of change of velocity of the flow of the fluid with respect to the
distance in the transverse direction (distance measured perpendicular to
the flow), also known as velocity gradient. The constant of
proportionality is known as the dynamic viscosity of the fluid denoted
by ‘µ’. The functional relationship between viscous shear stress and
velocity gradient is linear in a Newtonian fluid. This relationship may
be written as :
Where = viscous shear stress = dynamic viscosity of the fluid = velocity gradient across the flow
A Non-Newtonian fluid is a fluid which is different from the
Newtonian fluid as the viscosity of non-Newtonian fluids is dependent on
shear rate or shear rate history. In a non-Newtonian fluid, the
relation between the shear stress and the shear rate is different and
can even be time-dependent (Time Dependent Viscosity). Therefore, a
constant coefficient of viscosity cannot be defined.
Non-Newtonian fluids change their viscosity or flow behavior
under stress. If you apply a force to such fluids, the sudden
application of stress can cause them to get thicker and act like a
solid, or in some cases, it results in the opposite behavior and they
may get runnier than they were before. Removal of the stress causes them
to return to their earlier state.
Not all non-Newtonian Fluids behave in the same way when stress is
applied – some become more solid, others more fluid. Some non-Newtonian
fluids react as a result of the amount of stress applied, while others
react as a result of the length of time that stress is applied.
The generalized power law for all fluids can be written as:
Where K = flow consistency index
n = Fluid behavior index, n=1 for Newtonian fluids
Reynolds number of the flow is defined as the ratio of inertia forces to viscous forces.
Mathematically it is written as
Where = density of fluid v = velocity of fluid d = characteristic length = dynamic viscosity of fluid
The Reynolds number helps us to predict the transition between
laminar and turbulent flows. Laminar flow is highly organized flow along
streamlines. As velocity increases, flow can become disorganized and
chaotic. This is known as turbulent flow. Laminar flow occurs in flow
environments where Re < 2000. Turbulent flow is present in
circumstances under which Re > 4000. The range of 2000 < Re <
4000 is known as the transition range.
Most blood flow in humans is laminar, having a Re of 300 or less, it is
possible for turbulence to occur at very high flow rates in the
descending aorta, for example, in highly conditioned athletes.
Turbulence is also common in pathological conditions such as heart
murmurs and stenotic heart valves. Stenotic comes from the Greek word
"stenos," meaning narrow. Stenotic means narrowed, and a stenotic heart
valve is one in which the narrowing of the valve is a result of the
plaque formation on the valve.
The Womersley number, or alpha parameter, is another dimensionless parameter like the Prandtl number or Reynolds number
that has been used in the study of fluid dynamics. This parameter
represents a ratio of transient to viscous forces, just as the
Reynolds number represented a ratio of inertial to viscous forces. A
characteristic frequency represents the time dependence of the
parameter. The Womersley number may be written as.:[2]
Where
= Womersely Number
r = vessel radius
= fundamental frequency
= kinematic viscosity =
The flow profile becomes blunter near the centerline of the vessel in
high frequency flows, because the inertia forces become more important
than viscous forces. But viscous forces are still important near the
wall as here the velocity of the flow is almost zero due to the effect
of the wall and the no-slip condition. Moreover, it can be shown that
the transient forces become relatively more important than viscous
forces as the animal size increases.[2]
Medical imaging physics is also known as diagnostic and interventional radiology physics. Clinical (both “in-house” and “consulting”) physicists[10] typically deal with areas of testing, optimization, and quality assurance of diagnostic radiology physics areas such as radiographic X-rays, fluoroscopy, mammography, angiography, and computed tomography, as well as non-ionizing radiation modalities such as ultrasound, and MRI
