Ludwig Prandtl was born on February 4, 1875 and died on August 15, 1953. Ludwig Prandtl would have been 78 years old at the time of death or 140 years old today.
The flow's Mach angle is constant through a Prandtl-Meyer expansion wave.
The Nusselt number is proportional to the Prandtl number to the nth power, where n is a positive number less than one.
Prandtl number is dimensionless number, denoted by Npr.Npr = Cp (viscosity)/(thermal conductivity) Cp - specific heat, J per ( Kg Kelvin) viscosity in poise (gm per( cm sec)) thermal conductivity in Watt per (meter kelvin) Prandtl number is important in heat transfer.
The centrifuge was first invented in the late 19th century, with the first patent for a centrifugal separator being filed in 1864 by Antonin Prandtl. However, the modern centrifuge as we know it today, with improvements in design and functionality, was developed in the early 20th century.
"Baals wind tunnel" likely refers to a wind tunnel named after renowned aerodynamicist Ludwig Prandtl. Prandtl's work on wind tunnels in the early 20th century was foundational in understanding aerodynamics, and his name is often associated with wind tunnel research and design.
The ratio between the kinematic viscosity and the thermal diffusivity is called the Prandtl Number.
Antonin Prandtl, however Gustof de Laval invented the first "Modern" centrifuge. http://en.wikipedia.org/wiki/Centrifuge
