gasstroom

Gasstroom is a term used in Dutch-language contexts to describe the flow of gas through a system, or more generally a gas stream. It refers to a moving quantity of gas that can carry energy, matter, or information as it passes through pipes, ducts, reactors, or other equipment. In engineering and physics, a gasstroom is characterized by its flow rate, pressure, temperature, and composition, and may involve single-phase gas or gas with vapors or particulates.

The behavior of a gasstroom is governed by fluid dynamics and thermodynamics. Key properties include density, viscosity, heat capacity, and diffusivity, while the flow regime is described as laminar or turbulent depending on geometry, speed, and viscosity. Models often treat gases as ideal under certain conditions, but real-gas corrections are used for high pressures or low temperatures. Rate and quality of mixing, heat transfer, and chemical reactions can all influence the design and operation of systems handling a gasstroom.

Measurement and control involve instruments such as flow meters (volumetric or mass-based), pressure regulators, and temperature sensors. Gas composition may be monitored with analyzers, and downstream processing may include filtration, drying, condensation, absorption, or catalytic treatment to remove impurities or to achieve desired chemical reactions.

Applications span natural gas transmission, combustion exhaust and flue gases, HVAC air handling, chemical processing, and industrial manufacturing where inert or reactive gases are used. Safety considerations emphasize leak detection, ventilation, pressure relief, and compliance with applicable standards and regulations to manage flammability, toxicity, and environmental impact.
