Abstract:
The right selection of carburizing gas flow rates in the low-pressure carburization process is a key factor in terms of its efficiency. However, a correct calculation of the amount of carburizing gas required for uniform carburization of parts, taking into account the process temperature and batch size, is still problematic. For this reason, modern carburizing processes are carried out using an excessive belaying flow of carburizing gases. In this work steel parts (16MnCr5) were carburized in a variable-flow carburizing process (960 °C) individually matched to each segment of saturation. The e

Low-pressure vacuum carburizing adopts a pulse process mode to improve the carburizing efficiency and reduces gas and energy consumption. Carbon flux is the key to accurately control the time of strong infiltration and diffusion in each pulse. In order to obtain the carbon fluxes with various materials under diffident carburizing process conditions, an evenly segmented carbon flux method is proposed. A systematic study with each model using different materials (12Cr2Ni4A, 16Cr3NiWMoVNbE, and 18Cr2Ni4WA represent different initial carbon concentrations and different alloy compositions), carburi

Within the realm of demanding marine operations, tugboat chain sprockets have a vital function in guiding and controlling giant ships. Marine conditions provide considerable obstacles for chain sprockets, which are commonly constructed from low-carbon steel for their cost-effectiveness and mechanical appropriateness. One such problem is corrosion, which can result in material failure. AISI 1020, a low-carbon steel containing around 0.2% carbon, provides exceptional toughness and resistance to corrosion, especially for applications in mining and oil platforms.

Low-pressure carburizing followed by high-pressure quenching in single-piece flow technology has shown good results in avoiding distortions. For better control of specimen quality in these processes, developing numerical simulations can be beneficial. However, there is no commercial software able to simulate distortion formation during gas quenching that considers the complex fluid flow field and heat transfer coefficient as a function of space and time. For this reason, this paper proposes an algorithm scheme that aims for more refined results. Based on the physical phenomena involved, a nume

Gas-phase electron diffraction (GED) has remained the most valuable technique for the collection of structural information in the gas phase, for the last 70 years. Unfortunately, this structural technique had reached a limiting factor: the volatility of chemicals.  Therefore this work aims to provide new ways to overcome both the kinetic and thermodynamic aspects of this problem by the adoption of a new nozzle design and by the use of a reservoir. The new nozzle extends the capabilities of gas electron diffraction to compounds with lower vapour pressures or with vaporisation rates not adequate

Abstract:
An experimental study was carried out to characterize the scavenging behavior of a cross-scavenged, piston-aspirated, two-stroke, natural gas engine to aid in the development of computationally inexpensive simple scavenging models for onboard engine control by (1) studying the effects of changing operational parameters on the engine's scavenging performance, and (2) identifying the underlying phenomena driving the observed effects. Tracer based methods were used to quantify the scavenging and trapping performance of the engine - CO2 was used as a tracer for combustion products and pre-mixed fu

Abstract:
Large-bore, natural gas-fueled engines are used for gas compression at over 1700 compression stations across the US, and methane emissions have presented a challenge to their optimization over the years. A significant root of this problem has been linked to the level of air-fuel mixing in the main combustion chamber of these engines as poor mixing results in low combustion efficiency. High-pressure fuel injection is believed to be a significant way to improve air-fuel mixing in natural gas engine combustion chambers. The purpose of this present study is to determine the sensitivity of in-cylin

Abstract:
The natural gas industry operates over 8000 stationary large bore (bore greater than 14 in) natural gas engines for natural gas compression on pipelines and power generation. As emissions regulations become increasingly more stringent, the need for low cost methods for compliance demonstration arises. A PEMS model is one such approach. Research in this area has increased significantly during the last decade. PEMS models for this application utilize parameters commonly measured on industrial engines in the field to predict engine-out emissions. Monitoring emissions in this manner represents a s
