In this recently published paper, we noted few typing errors. In this recently published paper, we noted a few typing errors. These may be read as follows:

Q denotes the heat generation/absorption parameter when Q > 0/Q < 0.

Here, T h and T w are the temperatures of the upper and the lower walls.

In Eq. (10), it should read no τ 0 in the first term and no (T − T h ) in the second term on RHS.

The values of heat generation/absorption (δ) and modified heat generation/absorption (δ 1) parameters in Eq. (14) are

$$ {\displaystyle \begin{array}{l}\delta =\frac{Q\left(1- ct\right)}{\rho {c}_pa},\\ {}{\delta}_1=\frac{\tau_0Q}{\rho {c}_p}=\gamma \delta, \\ {}\gamma =\frac{\tau_0a}{\left(1- ct\right)}\end{array}} $$

These parameters (δ) and (δ 1) should be given different values.

There should be no δ, ε and δ 1 in the captions for Figs. 2a, 3 and 5.

    Deborah number in conclusion (3) is second grade parameter.
