From the article:
A specially designed producer gas carburetor is comprehensively analyzed for its mixing performance and response with a CFD modeling. The model is made up of a mixer chamber that has the essential orifices for air and fuel (producer gas) inlets to generate stable stoichiometric mixture at near to ambient conditions using the induction of the engine as the driving pressure differential for the flow, and tested for a case of engine of 25 kWe capacity. The CFD simulations are carried out followed with experimental studies to validate the analysis. The results show a consistency in the experimental data and the modeling has provided a good insight into the flow details and has paved way in optimization in the geometrical design to get a good mixing efficiency.
