Nusselt_number {TrenchR}

Nusselt Number

Description

The function estimates the Nusselt Number, which describes dimensionless conductance (Gates 1980).

Usage

Nusselt_number(H_L, D, K)

Arguments

H_L

numeric convective heat transfer coefficient (W m^-2 K^-1).

D

numeric characteristic dimension (e.g., body diameter) (m).

K

numeric thermal conductivity (W K^-1 m^-1).

Value

numeric Nusselt number.
