Prandtl number of water at 1 bara pressure, varying temperature given as °C or °F: . Prandtl number of water at 1, 10 and 100 bara (14.5, 145 and 1450 psia), varying temperature given as °C or °F: . Prandtl number of water at atmospheric pressure, temperature given as K, °C...
Plot the Pr number for CO2 at 40 °C and H2O at 400 °C at pressures from 0.01 to 60 MPa. Solution. The Pr number (Pr = Cpμ/k) is calculated from Eq. (8.17) and only depends on the properties of the fluid. At a given T and P, the thermodynamic state of the fluid is fixe...
They reveal a primary interest in a qualitative understanding of the gradual process of flow separation. Prandtl built a special water channel for observing the detachment of vortices from curved bodies. When he finally presented the boundary layer concept at the Third International Congress of ...
It would also be helpful to dispel the idea that a turbulent Prandtl number of unity was in any sense the “normal” value. We shall see [...] that a value of about 0.7 has a far stronger claim to normality. Perhaps, it is not a mere coincidence that the theoretical study of Yakho...

[18] found that small pipes yielded exchanges up to 18% higher than orifice nozzles (perforated plate) at stagnation zone. Experimental studies conducted by [11,14,24,25] with water and oil jets showed that the Reynolds number is not sufficient to fully account for injector diameter changes,...
However, the development and knowledge of THF models is limited. Most of the commercial codes rely on analogies between the turbulent momentum-thermal behaviour. This approach, which is accepted for moderate and high Prandtl number fluids as air and water (Pr=7), is not accurate when predicting...
