2. Abstract
In this project, a 3D geometry of the batch reactor is modeled to
simulate the fluid flow, temperature distribution, within the reactor.
The CFD analysis involves solving the Navier-Stokes equations along
with turbulence and energy models to capture complex flow
patterns, heat transfer, and chemical reactions.

7. Equilibrium Reactor
An equilibrium reactor is a model or conceptual framework used in chemical engineering
to simulate reactions that are governed by chemical equilibrium.
In such reactors, the composition of the reactants and products reaches a state where the
forward and reverse reaction rates are equal, meaning no net change occurs in the
concentrations of the species involved.
The main principle behind an equilibrium reactor is that it assumes the system achieves
equilibrium under the given conditions, allowing for the prediction of the final mixture of
products and reactants.
In process simulation tools, equilibrium reactors are used to model systems where the
reaction does not go to completion but reaches a balanced state. The software calculates
the composition of the outlet stream based on thermodynamic principles.
