Ferrofluids have been successfully used in the seals for rotary shafts, but few studies focus on the reciprocating motion seals. Since the completely different operational regimes, previous experiences on the rotary motions could not be directly applied on the cases for reciprocating ... Per saperne di più
It is frequently necessary to electrically heat gases; a convenient geometry is the familiar tube-in-shell heat exchanger, where the tube side is modified for electrical heater-rods, and the baffled shell side contains the flowing gas, as indicated in Fig. 1. However, this modification ... Per saperne di più
This paper describes how to numerically tackle the problem of counting and sizing particles by impedance measurement in an orifice–electrode system. The model simulate the particle dynamics submitted to strong hydrodynamic stresses through a microorifice and compute the voltage pulses ... Per saperne di più
Magnetorheological Finishing (MRF) is one of the precision finishing processes in which magnetic field is used to drive abrading forces for Finishing 2D and complex 3D surfaces. In this paper, Ball End Magnetorheological Finishing (BEMRF) has been analyzed for fluid behaviors under the ... Per saperne di più
The effective modeling of enhanced geothermal systems (EGS) requires the coupling of geomechanics, fluid flow and thermal processes. An understanding of the complete system with these coupled processes is vital, not just for reservoir stimulation targeted at enhancing reservoir ... Per saperne di più
Geothermal heat production from deep reservoirs (5000-7000 m) is currently examined, not only in Germany. Our reference set-up consists of two pipes within a single borehole: one for pumping. We examine a design, where a single borehole splits into two legs at a certain depth. The two ... Per saperne di più
Microfluidic devices and lab-on-a-chip (LOC) require the ability to transport or pump reagents or reaction products, the ability to effectively mix small volumes of fluid, and provide direct data display. Surface acoustic wave (SAW) driven acoustic streaming generated by a piezoelectric ... Per saperne di più
Heating or cooling of stored fluids by thermal energy exchange with the enclosing walls may be enhanced by improving the efficiency of energy transfer; energy loss to the ambient is equalized for all simulations. Buoyancy driven internal natural convective flow is assumed to be the main ... Per saperne di più
Evaporative coolers are viable alternative to air conditioners because of their low power consumption. However, in tropical humid environments the increased humidity that accompanies the cool air in the evaporative coolers causes an uncomfortable wet feeling, since it hinders the ...

In this paper, implicit Large Eddy Simulation (LES) based on finite-element analysis is performed in order to investigate two-dimensional circular cylinder incompressible flow. Implicit LES attempts time-dependent flow computation with no explicit turbulence model. Here, two types of ... Per saperne di più
