 have studied free convection
on flow past an accelerated vertical plate in the presence of viscous dissipative heat using perturbation method.
cannot be precisely measured or even estimated since there are too many unknown parameters, such as temperature distributions (or gradients), ventilation from other devices (or the air conditioning system) and surface conditions of the electrical drive.
Makinde  examined the transient free convection
interaction with thermal radiation of an absorbing emitting fluid along moving vertical permeable plate.
In this paper the three-dimensional laminar free convection
stagnation-point flow of a nanofluid on a general curved isothermal surface is considered.
 analysed free convection
flow with variable suction in presence of thermal radiation.

The airflow at the vicinity of the doctor is a complex interaction of the background ventilation flow and the free convection
flow around the body.
