Thermal diffusivity
Input(s)
k: Thermal Conductivity \((\mathrm{W} /(\mathrm{m} \mathrm{K}))\)
\(\hat{\mathrm{C}}_{p}\): Heat Capacity at Constant Pressure \((\mathrm{J} /(\mathrm{kg} \mathrm{K}))\)
\(\rho\): Density \(\left(\mathrm{kg} / \mathrm{m}^{3}\right)\)
Output(s)
\(\alpha\): Thermal Diffusivity \(\left(\mathrm{m}^{2} / \mathrm{s}\right)\)
Formula(s)
\[
\alpha=\frac{\mathrm{k}}{\hat{\mathrm{C}}_{\mathrm{p}} * \rho}
\]
