Dense Silicon nitride was investigated to determine the effect of its microstructural parameters and densification on thermo-mechanical properties and thermal stress resistance to fracture initiation during a hot or cold mechanical and thermal shock testing. The different materials and microstructures were obtained by changing the parameters such as the type of the powder, additive, forming p...

Preparing thermal comfort conditions in outdoor public spaces is one of the considerations of architectural design. If the constructed area does not support comfortable conditions in outdoor spaces, it will cause microclimatic problems for pedestrians and adjacent buildings. Regarding the different thermal comfort conditions in outdoor spaces in comparison with indoor, several indices have b...

ABSTRACT: The Ilex paraguariensis is a species native to Brazil, Paraguay and Argentine, valued by its positive effects on human health. Mate processing consists of the following stages: pre-drying (rapid drying at high temperature, known as sapeco operation), drying, milling. In order verify current process propose future improvements mate processing, thermal mass balance analysis were applied...

a lattice boltzmann method is applied to demonstrate the comparison results of simulating natural convection in an open end cavity using different hydrodynamic and thermal boundary conditions. the prandtl number in the present simulation is 0.71, rayleigh numbers are 104,105 and 106 and viscosities are selected 0.02 and 0.05. on-grid bounce-back method with first-order accuracy and non-slip met...

The study seeks to show how online remote condition monitoring helps to improve the maintenance system in a power plant from mainly predetermined and corrective approach to predictive maintenance and, the resultant benefits of its adoption. The findings clearly indicate the various aspects of online remote condition monitoring system which thermal power plants can consider to improve on plant s...

A hybrid thermal model for accurate estimation of thermal condition of cagerotor induction motors under non-standard supply systems has been presented. The developed thermal model is a combination of lumped and distributed thermal parameters which are available from motor dimensions and other physical constants. The thermal condition of the motor under non-standard supply systems such as unbala...
