The loss of energy over time by a → dynamical system, typically due to the action of → friction or → turbulence. The lost energy is converted into heat, raising the temperature of the system. See also: → Ohmic dissipation. → viscous dissipation.
Noun form of → dissipate.
Fr.: dissipation ohmique
1) A loss of electric energy due to conversion into heat when a current
flows through a resistance. Same as Ohmic loss.
→ Ohmic; → dissipation.
Fr.: dissipation visqueuse
A degradation of → mechanical energy that is irreversibly converted to → thermal energy due to → viscous forces in the → fluid. Viscous dissipation occurs in → turbulent flows.
→ viscous; → dissipation.
