Flödesteknik

Flödesteknik is the study and application of the behavior and control of liquids and gases in pipes, channels and related equipment. It encompasses the analysis, design and optimization of systems where fluid flow is essential, spanning from small-scale devices to large industrial installations.

Core concepts include fluid mechanics, transport of mass, momentum and energy, laminar and turbulent flow, Reynolds number, pressure drop and head loss, as well as energy efficiency. Methods commonly used are analytical solutions, computational fluid dynamics (CFD), scale-model experiments and various flow measurement and visualization techniques.

Common components and processes involve pumps and compressors, valves, flow meters, heat exchangers, nozzles and ducts. Applications span pipelines and chemical reactors, HVAC systems, water supply and wastewater treatment, and biomedical devices, reflecting the breadth of the field across energy, process engineering, environmental technology and infrastructure.

In education and research, flödesteknik is taught within mechanical, chemical or civil engineering programs. Current research areas include multiphase flow, porous media flow, microfluidics, CFD method development and the optimization of processes for energy efficiency, reduced emissions and sustainable operation of fluid systems. The field often emphasizes modeling, measurement and control to improve reliability, safety and performance in a wide range of fluid systems.
