Piston-Liner Crevice Geometry Effect on HCCI Combustion by Multi-Zone Analysis (open access)

Piston-Liner Crevice Geometry Effect on HCCI Combustion by Multi-Zone Analysis

A multi-zone model has been developed that accurately predicts HCCI combustion and emissions. The multizone methodology is based on the observation that turbulence does not play a direct role on HCCI combustion. Instead, chemical kinetics dominates the process, with hotter zones reacting first, and then colder zones reacting in rapid succession. Here, the multi-zone model has been applied to analyze the effect of piston crevice geometry on HCCI combustion and emissions. Three different pistons of varying crevice size were analyzed. Crevice sizes were 0.26, 1.3 and 2.1 mm, while a constant compression ratio was maintained (17:1). The results show that the multi-zone model can predict pressure traces and heat release rates with good accuracy. Combustion efficiency is also predicted with good accuracy for all cases, with a maximum difference of 5% between experimental and numerical results. Carbon monoxide emissions are underpredicted, but the results are better than those obtained in previous publications. The improvement is attributed to the use of a 40-zone model, while previous publications used a 10-zone model. Hydrocarbon emissions are well predicted. For cylinders with wide crevices (1.3 and 2.1 mm), HC emissions do not decrease monotonically as the relative air/fuel ratio ({lambda}) increases. Instead, maximum HC …

Prayer and Religion in the Public Schools: What Is, and Is Not, Permitted (open access)

Prayer and Religion in the Public Schools: What Is, and Is Not, Permitted

Few areas of constitutional law have proven to be as controversial and as subject to misinterpretation as that concerning the constitutionality of government-sponsored religious activities in public schools. In the last three decades the Supreme Court in five decisions and the State arid lower Federal courts in dozens of related decisions have attempted to articulate the 1 / meaning of the religion clauses of the First ~mendment- for a variety of such activities, including State-sponsored prayer, Bible reading, and religious teaching. Notwithstanding continuing political controversy over many of these decisions, they provide a fairly consistent interpretation and application of the First Amendment.

RF Gas Plasma Source Development for Heavy Ion Fusion (open access)

RF Gas Plasma Source Development for Heavy Ion Fusion

Presently the Heavy Ion Fusion Virtual National Laboratory is researching ion sources and injector concepts to understand how to optimize beam brightness over a range of currents (50-2000 mA argon equivalent). One concept initially accelerates millimeter size, milliamp beamlets to 1 MeV before merging them into centimeter size, ampere beams. Computer simulations have shown the final brightness of the merged beams is dominated by the emittance growth of the merging process, as long as the beamlets ion temperature is below a few eV. Thus, a RF multicusp source capable of high current density can produce beams with better brightness compared to ones extracted from a colder source with a large aperture and lower current density. As such, experiments have begun to develop a RF multicusp source capable of delivering one amp of extracted beam current. It is expected that it will require 10 kW of 13 MHz RF power delivered via a quartz shielded, one and half turn, four inch diameter antenna. Important considerations in the development of the source include the dependence of current density and beam ion temperature on consumed RF power and gas pressure. A fast rise time ({approx} 100 ns) for the extracted beam pulse must …
