Gas chromatography (GC) is a well-known and widely employed technique for separation and analysis of the gaseous and volatile components. Modern GC technique was firstly invented by James and Martin in 1952 and applied for the separation of amino …

The paper presents a thermo-gas-dynamic model of the gas chamber of automatic weapons using the gas extraction principle. The problem is solved using the differential form equation of the mass and energy conservations, the volume variation …

This paper presents the results for a model of a typical urban compressed natural gas (CNG) station obtained with the help of numerical methods on the assumption that the leakage explosion scenarios run under three orifice sizes. The simulation …

The power transformer is one of the key components of any electrical grid, and, as such, modern day industrialization activities require constant usage of the asset. This increases the possibility of failures and can potentially diminish the …

The development of supercomputers and parallel computing technologies has provided a fundamental increase in the capabilities of mathematical modeling of physical processes in ionized media. In particular, three-dimensional modeling based on the …

The authors have given results of experimental investigations into the gasification of a solid composite fuel in a superadiabatic reactor with a water-cooled condenser making it possible to collect and analyze gas-phase and liquid gasification …

A bottom-lit open top packed bed In-situ Gasification-Activation System with Staged Oxidizer Supply (IGAS-SOS) for co-generation of activated carbon (AC) and intrinsic hydrogen rich producer gas from coconut shells in a single step is …

It is the main problem in gas reservoir development to determine the reasonable gas production rate, which must be solved firstly. Volcanic gas reservoir in Xushen gas field is composed of contiguous superimposed volcanic rocks of different sizes …

Application of renewable energy to replace fossil fuels is an urgent issue to reduce greenhouse gas emissions, contributing to the implementation of the Net Zero strategy. Vietnam is a tropical country thus biomass is largely abundant. Therefore …

The world population has increased by 30 percent in this millennium (UNCTAD 2023), resulting in a natural increase in energy consumption. However, energy demand has grown at an even higher rate than the population. Global energy consumption has …

Gases behave ideally in the limiting conditions of high temperature and low pressure. An ideal gas does not undergo a phase transition to a condensed phase. The ideal gas remains a gas at all conditions of temperature and pressure. A real gas can …

The regional oil and gas accumulation processes in Central Sichuan are very complex due to multiple sets of source rocks, multiple sets of plays and multiple accumulation periods. This research focused on the structural evolution and reconstructed …

An Erratum to this paper has been published: https://doi.org/10.1134/S004060152403011X …

As a clean and efficient resource with large reserves, natural gas hydrate has gained worldwide attention in recent years. Unfortunately, the productivity prediction of NGH reservoirs based on traditional numerical simulation is time-consuming and …

In view of the problems of large error and lack of theoretical basis in the conventional evaluation methods for the gas injection capacity of gas injection wells in reservoir-type gas storage, under the condition of pseudo-steady seepage, it is …

Volcanic gas emission represents a source of hazard to humans and the environment. They occur both during volcanic unrest, eruptions and in quiescent stages of the volcanic activity. Therefore, it is a widespread and frequent threat. Many gas …

A three-dimensional mathematical model has been established for a novel metallurgy process coupling an annular gas curtain with swirling flow at tundish upper nozzle. The discrete phase model and volume of fluid model were applied to simulate the …

This paper presents the results of an experimental study on the addition of Hydrogen-Rich Gas (HRG) to a 4-stroke, 4-cylinder gasoline engine using a carburetor. The authors have designed and calculated the necessary HRG system for the engine; …

The work analyses Italy’s current strategies for gas supply to guarantee the energy security of the national market and its potential capacity for diversification. In the first part, having examined the Italian situation relative to domestic …

When gravity displacement gas invasion occurs in fractured reservoirs, it is easy to cause blowout accidents if not handled properly. Based on ANSYS software, a model of horizontal well intersecting vertical fracture was established to simulate …
