Experimental investigation on heating performance of heat pump for electric vehicles at -20 °C ambient temperature
(ELSEVIER LTD, 2015-07-29)
Since the performance of conventional air source heat pump (ASHP) for electric vehicles (EVs) is apt to decline sharply in low ambient temperature, it will consume more electricity of the cell, and affect driving mileage ...
Avaliação técnica e de custos do uso de injetor tipo venturi associado à bomba centrífuga versus bomba do tipo pistão na quimigação via pivô central
(2015-10-01)
The use of Venturi injectors is a common practice in chemigation in targeted irrigation systems, which generally operate at low pressures. Their use in larger systems, such as the center pivot, can be seen as an alternative ...
A flow injection procedure based on solenoid micro-pumps for spectrophotometric determination of free glycerol in biodiesel
(ELSEVIER SCIENCE BV, 2010)
A flow system designed with solenoid micro-pumps is proposed for fast and greener spectrophotometric determination of free glycerol in biodiesel. Glycerol was extracted from samples without using organic solvents. The ...
Influence of vegetable oil in the viscosity of biodiesel-a review
(2008-12-01)
Viscosity is a measure fluid resistance to flowing, affecting the fuel spray in the combustion chamber and, by this way, thus the formation of carbon deposits. The analysis of the influence of vegetable oil viscosity in ...

Operational Scheduling of Refined Products Pipeline Networks with Simultaneous Batch Injections
(Pergamon-elsevier Science Ltd, 2010-03-16)
Petroleum refined products are mostly sent from oil refineries to distribution depots by trunk pipelines. Pipeline networks usually involve multiple input and exit terminals, and even dual-purpose stations. Several pumping ...
