In the sugar industry, evaporators play an important role in the crystallization process of crystal sugar and heat economy. In this thesis two main objectives are intended to achieve it. The first objective was to determine the behavior of the field of velocities, temperatures and pressures of cane juice, of a two-phases system of a evaporator Roberts. The second objective was to determine the effect of inlet design on the juice to the evaporator heat transfer coefficient. As a study object was defined both the cane juice and Roberts evaporator. In order to computationally simulate the motion of a particle of sugarcane juice in a two-phase, CFX-ANSYS code was used, which calculates the flow field by the Finite Volume Method. Roberts evaporator of 1050 m2 in Industrial Pucalá in Lambayeque was used, which conditions of both cane juice and vapor was recorded flow. To determine the effect ...

Welding constitutes a type of permanent joint in the assembly process in the secondary manufacturing industry such as construction for the manufacture of automobiles, aircraft, bridges, tanks, ships, pipes, among others. The objective of this research was to compare the mechanical tensile strength and hardness of welded specimens. The mechanical traction was to evaluate the resistance to breakage of the weld seams by the MIG/MAG process versus the SMAW welding process, on ASTM 36 base material. The hardness was to determine the plastic deformation of the area affected by heat during the fusion process. For this purpose, the universal testing machine was used to determine the stress-strain relationship of each process; while a hardness tester was used for hardness. In this experiment, 12 welded specimens and two non-welded control specimens were used to determine the quantitative deviatio...
