Lendülettranszport

Lendülettranszport is a Hungarian term that translates to "momentum transport" in English. It refers to the physical process by which momentum is transferred between different parts of a system or between interacting systems. This phenomenon is fundamental in many areas of physics, including fluid dynamics, solid mechanics, and thermodynamics.

In fluid dynamics, momentum transport is responsible for phenomena like viscosity, where the motion of one layer of fluid influences adjacent layers. This occurs due to the random motion of molecules and their collisions, which effectively transfer momentum. In solids, momentum transport can be seen in the propagation of mechanical waves and in the effects of stress and strain. In a broader sense, it is also related to the transfer of kinetic energy.

The concept of momentum transport is closely linked to conservation laws, particularly the conservation of momentum. According to this principle, the total momentum of an isolated system remains constant unless acted upon by external forces. Lendülettranszport describes the internal mechanisms by which this conserved momentum is distributed and redistributed within the system. Understanding lendülettranszport is crucial for analyzing the behavior of complex physical systems and for developing predictive models in various scientific and engineering disciplines.
