1. Application of optimization for improvement of the efficiency of louvered-fin compact heat exchangers
Abstract A few decades ago, the product development process was just based on a trial and error procedure, and the designer's experience. The need for a new way to design and manufacture more economical and sustainable products corroborates increasingly to a new vision of how to create new products for the benefit of society. Modern numerical tools allow gre

2. 3D-CFD simulation and neural network model for the j and f factors of the wavy fin-and-flat tube heat exchangers
A three dimensional (3D) computational fluid dynamics (CFD) simulation and a neural network model are presented to estimate the behaviors of the Colburn factor (j) and the Fanning friction factor (f) for wavy fin - and - flat tube (WFFT) heat exchangers. Effects of the five geometrical factors of fin pitch, fin height, fin length, fin thickness, and wavy amp

3. Study of hydrodynamics and heat transference from liquid whole egg through plate with three formats chevron / Estudo da hidrodinamica e transferencia de calor do ovo integral liquido atraves de placas com tres formatos chevron
At this work are showed the heat transference and hydrodynamics of liquid egg flow between ducts with corrugated walls, simulating plate heat exchangers. The contour conditions admitted was the constant temperature in the walls during the fluid heating. The whole egg rheology was experimentally determinated in a extend temperature range (289 ? 335K). The egg

4. Desenvolvimento de leitos fixos a base de crisotila para reatores continuos
The addition of fiber glass, admixed with activated chrysotile improves the structural properties of packed-beds, resulting in highlys stable bases for use as continuous reactor nucleus. The oxidizing capacity of MnO2 and TiO2 immobilized onto chrysotile in continuous reactors stabilized with fiber glass was investigated. Methanol, ethanol, n- propanol, i-pr

5. Estudo de otimização das operações com tubo flexivel e nitrogenio
This work presents a study about the flow phenomena in jet-lifting with the purpose to reduce the nitrogen consumption, to maximize the fluid recovery and to reduce the operation time. A column of tests was designed and built, with a external 2.441 in 1D tubing pipe and a internal 1.0 in OD coiled tUbing, simulating the real situation of the jet-lifting oper
