The aim of this research was to study the energy flow and the modelling of energy use in broiler production in the Guilan Province of Iran. The data were gathered through interview with 25 broiler farm managers out of a total of 146 broiler producers in Rasht, the center of Guilan Province, Iran. The effect of broiler farm size at three levels—small (˂20,000 birds), medium (20,000–30,000 birds)...

In this paper a rotational, radial-flux energy harvester incorporating a three-phase generation principle is presented for converting energy from water flow in domestic water pipelines. The energy harvester together with a power management circuit and energy storage is used to power a smart metering system installed underground making it independent from external power supplies or depleting bat...

present paper investigates the numerical solution of two-dimensional unsteady compressible navier-stokes equations by a new scheme based on the finite volume method. kinetic energy preserving (kep) scheme is introduced for solving the supersonic and transonic external compressible flow field on very fine grids (with a number of cells of the order of the reynolds number) without artificial dissi...

A new electromagnetic energy harvester for harnessing energy from flow induced vibration is developed. It converts flow energy into electrical energy by fluid flow and electromagnetic induction. A finite element model for estimation of the generated voltage of the energy harvester is developed. A prototype of the energy harvester is fabricated and tested. Experimental results show that an outpu...

At lower relative (i.e., non-dimensional) frequencies, four propagating waves exist in fluid-filled pipes. Each of these waves carries energy in the pipe wall, while three waves carry energy in the fluid as well. The otherwise fairly complex dispersion laws for waves in pipes simplify in the frequency region considered to simple rodand beam-type laws. It is shown that these laws can be determin...

This study focuses on the numerical analysis of a high efficiency Energy Harvesting device, based on piezoelectric materials, for the sustainability of smart buildings, structures and infrastructures. Before that, a comprehensive literature review on the topic takes place. The device consists in an aerodynamic fin attached to a piezoelectric element that makes use of the air flow to harvest ene...

Computed near-field values of Poynting’s vector and electric and magnetic field intensities for a linear dipole are displayed in a way that aids visualization of the radiation process. The fields are computed for time-harmonic excitation, but are shown as a function of time to demonstrate the spatial ebb and flow of the fields around the dipole. By this means, the distinction between near and r...
