1. PREDICTION OF COAL SLURRY PIPELINE TRANSPORTATION GRADING REDUCTION AND ITS INFLUENCE ON PIPE TRANSPORTATION PARAMETERS
Abstract Coal slurry pipe, being a new type of energy transportation mode, changes of the particle composition and the effect on other parameters are worth studying. Comparison of ring tube test measured data and batch grinding model simulation data shows that batch grinding model can predict the coal particle gradation to a certain extent. The effect of col

2. Characterization of a pediatric rotary blood pump
Abstract Introduction A ventricular assist device (VAD) is an electromechanical pump used to treat heart failures. For designing the physiological control system for a VAD, one needs a mathematical model and its related parameters. This paper presents a characterization procedure for determining the model parameter values of the electrical, mechanical, and

4. Tratamento de Ãgua residuÃria de fecularia em reator anaerÃbio com leito fixo de pedras de calcÃrio dolomÃtico / Starch wastewater treatment in anaerobic reactor containing Dolomitic limestone
The cassava processing for starch or flour production generates some wastewater (manipueira) with high organic load and toxic compounds, which cause environmental degradation. In the western Paranà region, there are several starch factories, so its waste generation is a concern for the correct treatment and disposal. Thus, anaerobic reactors are a cost-effe

10. Estudo experimental de uma bomba operando como turbina para acionamento de bombas centrífugas submersas / Experimental study of a pump as turbine to drive centrifugal submersible pumps
O método de elevação artificial através do bombeio centrífugo submerso (BCS) é amplamente conhecido na produção de petróleo. Uma alternativa a este método é o hydraulic submersible pump (HSP) que consiste de uma bomba submersa acoplada ao mesmo eixo de uma turbina hidráulica, que é acionada através do fluido a elevada pressão fornecido por uma

11. Balanço hídrico e energético de um sistema predial de aproveitamento de água de chuva / Water and energy balance of a rainwater harvesting system for a building gutter
The use of rainwater as an alternative source of water supply is a practice on the rise, mainly for its importance in conservation of water resources. However, the user often ignores the energy that this system may require, and depending on its design, can be considered a relevant factor in its application. The conceptions and components of a rainwater harve

12. MODELO HIDRÁULICO BASEADO NO MÉTODO DAS CARACTERÍSTICAS E ALGORITMOS GENÉTICOS PARA OTIMIZAÇÃO DA OPERAÇÃO DE REDES DE ABASTECIMENTO DE ÁGUA E DE ESTAÇÕES DE BOMBEAMENTO
A hydraulic model was developed for simulation of water supply networks using the Method of Characteristics (MOC), introducing new features to the CALHIDREDMT model, proposed by Righetto (1994). The model uses the concept of pseudo-transient, using a fictitious value for the wave celerity. Simulations were performed in networks equipped with reservoirs, tank
