Pumping stations play an important role in agriculture development projects. Performance of the pumping stations should satisfy water requirements, and management. There are many problems face these pumping stations affecting their reliability and stability. Hydraulic problems are the most important item in the field of pumping station operation and design. Motivation of this research was prese...
Small-angle X-ray scattering (SAXS) was performed on single-crystal chemical vapor deposition (CVD) diamonds with low nitrogen concentrations, which were fabricated by microwave plasma-assisted chemical vapor deposition at high growth rates. High optical quality undoped 500 µm-thick single-crystal CVD diamonds grown without intentional nitrogen addition proved to be excellent as windows on SAXS...
Low Density Growth of Graphene by Air Introduction in Atmospheric Pressure Chemical Vapor Deposition
In this study, the silicon dioxide was deposited on the silicon substrate by metal-organic based plasma enhanced chemical vapor deposition (PECVD) method at the low temperature. The metal-organic tetraethoxy-silane (TEOS) was used as a silicon precursor in liquid state. In addition, oxygen and argon were used as ambient gases. Effects of the working pressure and O2/TEOS pressure ratio on the ch...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
Low-pressure sputtering and ionized vapor deposition processes create atomic fluxes with kinetic energies in the 1.0–20 eV (and above) range. The impact energy of these hyperthermal atoms significantly effects the surface morphology and structure of vapor deposited films. Recent molecular dynamics simulations of metal atom interactions with a metal surface have established the energy and angula...
