How to Evaluate Local Stanton Number?

Local Stanton Number evaluator uses Local Stanton Number = Local Heat Transfer Coefficient/(Density of Fluid*Specific Heat at Constant Pressure*Free Stream Velocity) to evaluate the Local Stanton Number, The Local Stanton Number formula is defined as the function of local heat transfer coefficient, density, specific heat capacity and free stream velocity. The Stanton number, St, is a dimensionless number that measures the ratio of heat transferred into a fluid to the thermal capacity of fluid. The Stanton number is named after Thomas Stanton (engineer) (1865–1931). It is used to characterize heat transfer in forced convection flows. Stanton number indicates the degree of amount of heat delivered by fluid when there is heat transfer between solid surface and fluid. The greater Stanton number is, the more effectively heat is transferred. Local Stanton Number is denoted by St_x symbol.
