In the above paper, the energy equation (see Eq. (3) in Ref. [1]) is as follows:
∂T∂t+u∂T∂x+v∂T∂y=1ρcp∂∂y(κ∂T∂y)+Φρcp
(1)

where T is the fluid temperature, t is the time, u and v are the velocity components in the x and y directions, respectively, ρ is the fluid density, cp is the specific heat, κ is the thermal conductivity, and Φ is the heat source.

The units of temperature are
[T]=Kelvin (temperature)
The units of time are
[t]=sec(time)

Therefore, the units of (Φ/ρcp) are K s−1 in order that this term is compatible...
