Title: Correction of the Preston equation for low speeds

Abstract

According to Preston [J. Soc. Glass Technol. 11, 214 (1927)], the wear on a glass point in the polishing process is proportional to the work given by frictional force between glass and tool. He supposed that the frictional coefficient is a constant value. To verify this hypothesis, we measured the dragging forces applied to a tool as a function of the relative speed between a rotating glass and the tool center. To reproduce these experimental results, it was necessary to propose a new model, for which the frictional coefficient has a Gaussian dependence with relative speed. Therefore the wearing Preston equation has to be modified in order to include the frictional coefficient as a function of the relative speed.

  • In the combustion of artificial graphite at temperatures between 430 and 700 deg C and at oxygen pressures of 10/sup -2/ mm Hg, the oxides CO and CO/sub 2/ are the primary products produced. When the combustion velocity evolves at constant temperature and pressure, following degassing, there is a linear relationship or proportionality (according to the graphite) between the formation velocities of CO and of CO/sub 2/ in a V/sub CO/ vs. V/sub CO2/ diagrams the experimental points are placed on the straight line called the ''combustion line.'' The slope of these lines is independent of the pressure of themore » oxygen in a certain pressure region. The values of the slopes, which vary with the temperature (thermal coefficient of 6 kcal), are equally sensitive for the different graphites studied. The chemisorption of low quantities of hydrogen has the effect of diminishing the combustion velocity. The corresponding experimental points are always placed on the same combustion line.

  • In this paper a theoretical and experimental investigation of the flame speeds of low-cetane fuels during the initial stage of heat release in a Diesel engine is described. This information is important for developing a fundamental background in the understanding of fuel injection rate-controlled heat release in a Diesel engine. In this study, a theoretical model based on droplet size, turbulent intensity, and equivalence ratio was developed for the flame propagation through a fuel droplet/air matrix. The results of the theoretical model was compared to experimental high-speed photographs of flame growth in a Diesel engine. For successful injection rate controlledmore » heat release to occur using pilot injection, the model determined that the combustion zone due to a pilot fuel spray must flow to a distance of at least 30 orifice diameters from the nozzle tip before the main injection event can take place. Results of the model were verified by experiment for the two limiting cases of X/D less than 30 and X/D greater than 30. As expected, rate-controlled heat release was achieved for the case of X/D less than 30. However, for the case of X/D greater than 30, the main fuel injection ignited upon injection into the cylinder, and heat release was controlled by rate of injection.« less
  • Data from an ongoing model validation program for dispersion of pollutants from roadways in Texas show pollutant concentrations do not increase as rapidly with decreasing wind speed as predicted by most models which are based on a Gaussian formulation. In fact, the actual ground level concentration may decrease with decreasing wind speed when the speed drops below some critical value. The Texas data should be sufficient to address many of the difficulties that are inherent to Gaussian models at low wind speeds.
