Adiabatic Temperature Rise

Maximum increase in temperature that can be achieved. This increase only occurs when the substance or reaction mixture decomposes completely and at adiabatic conditions. The adiabatic temperature rise follows from:

DTad = co o -DHr / r o Cp

In case of pure organic substances (Cp Å 2 kJ/kg K) the adiabatic temperature rise is often approximated by DTad = DHr / 2 with -DHr in kJ/kg.
