One of the methods to recover oil from medium and low viscosity in complex reservoirs uses air injection leading to oil combustion. In this case the oxygen in the air burns the heavier components of the oil, generating a heat wave leading to vaporization of lighter components. The combustion mechanisms are different for light oils, where evaporation is dominant, whereas for medium non-volatile ...

Lake Victoria is the largest tropical lake in the world and is very important for environment and economy in East Africa. The hydrodynamic processes in the shallow (40-80 m deep) water system are unique due to its location at the equator which makes Coriolis effects noticeable also for vertical transport. The limited river inflow, and the large surface area compared to its volume make Lake ...

Study of interaction of drops and bubbles with electric field is important for understanding the physics involved in various physical phenomenas and industrial processes. Important applications arise in colloidal systems (Miller and Scriven, 1970), meteorology and cloud physics (Sartor, 1969), electrostatic spraying of liquids (Balachandran and Bailey, 1981), power engineering applications ...

A mathematical model based on a finite element method (FEM) is presented as an initial approach for a system converting waste heat energy into chemical energy. This system consists of a pyroelectric LiNbO3 plate placed into a cylinder which undergoes a laminar water flow with an appropriate periodic heat source. It solves the heat transfer equation in non-isothermal flow, where the density of ...

Coalescence of droplets is a widely investigated phenomenon. In inkjet printing micrometer sized droplets are deposited on a substrate which when positioned close enough to each other will coalesce and mix. Little is known about the flows and mixing behaviour within these small droplets. In this investigation we follow the time evolved coalescence of two droplets with volume ratios ranging from ...

Internal combustion engine components have been a main research interest over many decades. The structural mechanics and dynamics of the piston rings has been a large focus of work in order to gain a greater understanding of the how the piston ring dynamics affect the piston ring. Piston rings are often coated to reduce the level of wear on the ring as they will suffer substantial levels of ...

Diabetes mellitus affects 387 million people across the world according to the latest estimates of International Diabetes Foundation. Insulin is one of the major drugs required to keep the glucose level within desired limits in a diabetic patient. Insulin is generally administered to a patient as a subcutaneous injection and consists of two forms namely, basal and bolus. The basal dosage is ...

An autonomous gas-heater for outdoor environments was selected as a test-case for cogeneration in gas-heaters and stoves, permitting installation and operation without need of an electrical network connection. A thermoelectric generator (TEG) was designed, converting part of produced heat into electrical power for auxiliaries (ventilation) or ancillary functions (illumination). Design approach, ...

The Microwave Electrothermal Thruster (MET) is a space electric propulsion device that uses an electromagnetic resonant cavity within which a free-floating plasma is ignited and sustained, heating a propellant gas that is that exhausted out of a gas-dynamic nozzle. For an empty cavity it is fairly straightforward to accurately calculate the cavity’s resonant frequency and describe the ...
