Hello !
I'm studying the forest fires, and I found an equation but there is something I don't understand. The equation is obtained thanks to energy conservation, and it is something like this : ρC dT/dt = h(T-T0) - Q Ys Aexp(-Ea/RTs)
The first term is the volumic enthalpy, the second is due to convection and the third to reaction.
What I can't understand it is that the first and the third terms are in W/m3, while the second is in W/m²
So why can we write that? Is it a particular h?
Thank you very much !
