Torch ignition systems in spark-ignition engines represents an interesting option in the efforts to reduce pollutants emission and specific fuel consumption. Based on this idea, this paper presents a 3D model of a prechamber created for a spark-ignition engine and focuses on the numerical analysis of the fluid flow inside the modified chamber. This kind of analysis is very important once it allowed evaluating aspects like turbulence parameters, pressure inside the chamber and prechamber, fluid recirculation and a possible prechamber’s geometry for the engine. The studies were done in a four valve Single Cylinder Research Engine – SCRE. For the numerical modeling and fluid flow investigation was used STAR-CD software. Results show higher values of tumble ratio and kinetic energy with the prechamber.

The fluid flow of an A356 semi-solid aluminum alloy filling a die consisting of four tensile test bars was investigated. Numerical simulations were carried out by implementing a mathematical model in a finite element software. Additional simulations were also obtained with a physical model in which tomato paste was used as the analogue fluid for the semi-solid aluminum. The modeling results were complemented by a series of experiments where tensile test bars were produced from semi-solid aluminum with a high pressure die casting press. The correspondence observed with the two modeling approaches and the casting experiments is discussed along with the effect the die geometry had on the flow patterns.
