in this paper, free convection in an inclined stepped chamber has been studied. one wall of this enclosure is kept cold and the opposite wall equipped with constant heat source. the remaining walls are maintained adiabatic. there is one adiabatic step on the bottom wall. the aim of the present study is to forecast the effect of raleigh number, slope of enclosure, step dimension, and heat source...

application of feed pellets in animal and aquatic farming industries has grown because of both the physical and the nutritional benefits it provides. development of feed pellets manufacturing industry is also considerable. steam conditioning process, which plays an important role in pelleting production, includes heating feed particles, adding moisture, and mixing the mash. pellets cooling and ...

The Time Difference of Arrival (TDOA) method has been widely used for sound source localization. However, because of the Doppler-effect, the TDOA method cannot be directly used for locating moving sound sources. This paper develops a moving sound source localization method based on TDOA, combining with Doppler-effect elimination and source plane scanning. This method is suitable for locating so...

the three-phase-lag model and green–naghdi theory without energy dissipation are employed to study the deformation of a two-temperature fiber-reinforced medium with an internal heat source that is moving with a constant speed under a hydrostatic initial stress and the gravity field.  the modulus of the elasticity is given as a linear function of the reference temperature. the exact expressions ...

Several approaches are available for estimating soil water flux indirectly (Nielsen et al., 1973; Bresler, 1973), A method is presented for measuring soil water flux density (J ) but these approaches can be time consuming, mathematwith a thermo-TDR (time domain reflectometry) probe. Constant heat input during a small time interval (15 s) is used to emit a heat ically complicated, and measuremen...

As a historic challenge for humans, Martian colonization has been initiated by nuclear energy. A moving power plant could be imaginable known as reactor rover. The design of the rover performed where important matter is how to make caterpillar move and its facilities. Hence slider length contact point are proposed. normalized heat transfer analyzed slide they 1.0 10.0, respectively. Although pr...

In submerged arc welding process, the understanding of temperature distribution is essential in order to control the dimension of heat affected zone and to get the required weld bead shape and size etc. Moreover, the temperature profile is required to estimate the stress distribution in thermo mechanical analysis of the process. In this work, a numerical solution for moving heat source with Gau...
