Periods
Stokes (and Navier)
Added Newtonian viscous term to the
equation of motion, the fluid motion
governing equation
i.e. Navier‐Stokes equation is
named after them.Ludwig Prandtl
Pointed out that fluid flows with small viscosity, such as
water flows and airflows, can be divided into a thin viscous
layer (or boundary layer) near solid surfaces and interfaces,
patched on to an early in viscis outer layer, where
the Euler and Bernoulli equations apply.Archimedes (285-212 BC)
Postulated the parallelogram law for
addition of vectors
and the laws of buoyancy.
He further applied them to
floating and submerged objects.Leonardo da Vinci
Stated the equation of conservation of mass in
one‐dimensional steady‐state flow.
He experimented with waves, jets, hydraulic jumps,
eddy formation, etc.Edme Mariotte
Built the first wind tunnel
and tested models in it.Isaac Newton
Postulated his laws of motion and the law of viscosity of
linear fluids, now called Newtonian.
The theory first yield the friction less assumption
which led to several beautiful mathematical solutions.Leonhard Euler
Developed both the differential equations of motion
andtheir integral form, now called Bernoulli equation.William Froude
Together with his son
developed laws of
model testingLord Rayleigh
Proposed dimensional analysis.Osborne Reynolds
Published the classic pipe experiment
and showed the importance of the dimensionless
Reynolds number, named after him.Navier (and Stokes)
Added Newtonian viscous term to the
equation of motion, the fluid motion
governing equation,
i.e. Navier‐Stokes equation is
named after them.
