to reduce the storing space and handling costs for hay/straw bales, recompressing the original bales after adequate hay drying is recommended. in this project, a recompression machine was designed, constructed and evaluated. solidwork and nastran software were employed to model, and to analyze the stresses in the components of the machine, respectively. the components of the machine consisted o...
The emitter discharge is affected by parameters such as pressure, irrigation water temperature, manufacturer’s coefficient of variation, and emitter clogging. In order to study the effects of irrigation water temperature on emitter discharge and to determine the discharge-pressure variations and manufacturer’s coefficient of variations, an experimental trickle irrigation system was designed and...

Measurements are presented of ion energy distributions produced within a prototype NSTAR discharge chamber as a function of its operational parameters. The goal of this effort is to document the ion energy distribution characteristics and determine features that could cause rapid sputter erosion of discharge chamber components. Ion energy distributions were measured with a Comstock model AC-901...
A spatial and temporal numerical simulation has been carried out of a pulsed (100% modulated), rf inductively coupled plasma discharge in argon, connected to an additional (ballast) diffusion chamber of much larger volume. It is demonstrated that during the active phase, the presence of the large ballast volume has a small impact on the parameters of the plasma in the smaller discharge chamber....
In this process after making proper chamber to produce plasma in d.c. Glow regime and readiness of samples and doing microhardness and PIXE analyzes, samples nitriding began in different conditions. The hardness changes and the depth of hardened layer of 321, 316 and 304 steels are studied as a function of discharge parameters [8, 9]. The plasma was produced using a mixture of N2 and H2 gases...
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...
The consideration of the convective heat transfer in the suction and discharge region of a compressor is handled differently in the literature. Commonly used are correlations for a steady state turbulent flow through a pipe like Chrustalev et al. (1998), Xin et al. (2000), Link et al. (2007). Here it is a point of principle whether such an approach is justified. Subjects of the present work are...
A dual-chamber anode structure is proposed in order to solve two performance problems of the conventional passive micro direct methanol fuel cell (μ-DMFC). One of the problems is the unstable performance during long time discharge. The second problem is the short operating time. In this structure, low concentration chamber is filled with methanol solution with appropriate concentration for the ...
