Abstract

By definition, the Prandtl number ( P r $Pr$ ) is given as P r = μ f C p f / k f $Pr = \mu _f C_{pf}/k_{f}$ . Following the dynamical property of blood in line with Table 1 below in [1], the specific heat capacity of blood C p $C_p$ is 3594 J / κ kg = m 2 s − 2 κ − 1 $\mathrm{J}/\kappa \mathrm{kg}={\mathrm{m}}^{2}\hspace*{0.20202em}{\mathrm{s}}^{-2\hspace*{0.20202em}}{\kappa}^{-1}$ , the blood thermal conductivity k f $k_f$ is 0.492 W / m κ = kg ms − 3 κ − 1 $\mathrm{W}/\mathrm{m}\kappa =\mathrm{kg}\hspace*{0.20202em}{\mathrm{ms}}^{-3}\hspace*{0.20202em}{\kappa}^{-1}$ , and the blood dynamic viscosity μ f $\mu _f$ is 0.00313 kg m − 1 s − 1 $\mathrm{kg}\hspace*{0.20202em}{\mathrm{m}}^{-1}\hspace*{0.20202em}{\mathrm{s}}^{-1}$ . As a result, the Prandtl number for blood is Hence, the Prandtl number in [1] is 22.86 instead of 1. Also, taking the value of Eckert number ( E c $Ec$ ) to be 0.1, then by definition of Brinkmann number (Br) given as B r = P r × E c $Br=Pr \times Ec$ , the Brinkmann number (Br) is taken to be 2.3. Likewise, the value of ϕ = 0.1 $\phi = 0.1$ should be replaced with ϕ = 0.05 $\phi = 0.05$ . It is also worth mentioning that the corrections here only affect the magnitudes of the graphs and do not affect the discussion of results and conclusions of the paper. We are very much thankful for the initiative of the editors to identify the issue with our published article.
