Online aerodynamics calculator to calculate shape factor by using displacement thickness and momentum thickness as input values.
The Shape factor (also know as view factor), refers to a value that is affected by an object's shape but is independent of its dimensions. It is a purely geometric quantity and is independent of the surface properties and temperature and It indicates how much more load or torque can be carried by the structural shape than by the same mass of material with a square cross section.
Formula:
where,
H = shape factor
δ* = displacement thickness
θ = momentum thickness
H = shape factor
δ* = displacement thickness
θ = momentum thickness
