Abstract: This paper presents a methodology to determine and to formalize all the variables involved in a CFD model of a 2-stroke diesel engine. The formalization includes the establishing of the values domain and the research of relations between the variables. The formalization can be followed by a reduction of the variables and the ranges of values. The methodology concludes on the qualification of the model. The methodology has to be used before solving the model. It helps not to forget any variable and to well understand the characteristics of the final model. It also provides the validity domain of the model and the limits of its exploitation. The methodology is applies to the 2-stroke Diesel engines to optimize its design and characterize the aerodynamics inside the combustion chamber.

Abstract: In this paper, the strength of concrete cubes and cylinders cast using M40 grade concrete and reinforced with recron3s, polypropylene fibers and mineral admixtures have been presented. Also, hybrid fibers with recron3s and polypropylene have been used in concrete matrix to study its impact on strength and durability properties. The recron3s, polypropylene and hybrid [polypropylene and recron3s] fibers of various proportions i.e., 1% of recron3s fiber, 1% of polypropylene fiber (Boasee fiber) and 1% of hybrid fibers each of 0.5% by volume of cement with admixtures of 1% by weight of cement have been used in concrete mixes. The result obtained has been analyzed and compared with the control specimen (0% fiber). It clearly shows the compressive strength values for M40 grade without and with fibers.
