Is the problem in the small time step size? Try using the implicit heat transfer solver, imphtc=1. Also, I would use a the constant viscosity model, IFVISC=1, instead of the temperature or strain rate dependent. Another question, do you think turbulence is important in such small scales?

turbulence is important ...
It will affect the results, such as stomatal...
