Simulate Chemical Equilibrium

ODEKO allows the user to compute the thermodynamic and transport properties along the nozzle axis employing chemical equilibrium. This method assumes that reactions are infinitely fast (valid if they are much faster than the fluid velocity). Along with this option the user is able to "freeze" the flow at any point in the nozzle, after which it will be considered that no more reactions take place (infinitely slow reaction speed). This method offers very reliable results for a wide variety of propellants.

Simulate Finite-Rate Chemical Kinetics

If the user desires greater precision, ODEKO offers the option to compute the variables along the nozzle with finite rate chemestry. This method computes the reaction rates of the various molecules conforming the mixture at every point, resulting in a much better description of the evolution of the system. This method requires the user to specify a kinetic scheme, for which a stronger background on the topic is benefitial (check the documentation!). This method offers better results as it is closer than reality than the assumptions of infinitely fast reactions (chemical equilibrium) or infinitely slow reactions ("frozen" flow).

Simulate Solid Motor Combustion

If the user simulates a solid propellant rocket motor with a given grain geometry, ODEKO is able to compute the evolution of the rocket motor properties as a function of time. Moreover, the user may also optimize the nozzle for a variety of target parameters.
