  2. SRM Engine Suite - Wikipedia

    en.wikipedia.org/wiki/SRM_Engine_Suite

    The software is based on the stochastic reactor model (SRM), [17] which is stated in terms of a weighted stochastic particle ensemble. SRM is particular useful in the context of engine modelling [18] as the dynamics of the particle ensemble includes detailed chemical kinetics whilst accounting for inhomogeneity in composition and temperature space arising from on-going fuel injection, heat ...

  3. Kinetic theory of gases - Wikipedia

    en.wikipedia.org/wiki/Kinetic_theory_of_gases

    The kinetic theory of gases is a simple classical model of the thermodynamic behavior of gases. Its introduction allowed many principal concepts of thermodynamics to be established. It treats a gas as composed of numerous particles, too small to be seen with a microscope, in constant, random motion.

  4. Gas kinetics - Wikipedia

    en.wikipedia.org/wiki/Gas_kinetics

    Gas kinetics is a science in the branch of fluid dynamics, concerned with the study of motion of gases and its effects on physical systems.Based on the principles of fluid mechanics and thermodynamics, gas dynamics arises from the studies of gas flows in transonic and supersonic flights.

  5. Internal combustion engine - Wikipedia

    en.wikipedia.org/wiki/Internal_combustion_engine

    Gasoline engines take in a mixture of air and gasoline and compress it by the movement of the piston from bottom dead center to top dead center when the fuel is at maximum compression. The reduction in the size of the swept area of the cylinder and taking into account the volume of the combustion chamber is described by a ratio.

  6. Gas engine - Wikipedia

    en.wikipedia.org/wiki/Gas_engine

    Gas Engine for Electric Power Generation from INNIO Jenbacher Model of an S-type Hartop gas engine. A gas engine is an internal combustion engine that runs on a fuel gas (a gaseous fuel), such as coal gas, producer gas, biogas, landfill gas, natural gas or hydrogen. In the United Kingdom and British English-speaking countries, the term is ...

  7. de Laval nozzle - Wikipedia

    en.wikipedia.org/wiki/De_Laval_nozzle

    The analysis of gas flow through de Laval nozzles involves a number of concepts and assumptions: For simplicity, the gas is assumed to be an ideal gas. The gas flow is isentropic (i.e., at constant entropy). As a result, the flow is reversible (frictionless and no dissipative losses), and adiabatic (i.e., no heat enters or leaves the system).

  8. Propulsive efficiency - Wikipedia

    en.wikipedia.org/wiki/Propulsive_efficiency

    In aerospace engineering, concerning aircraft, rocket and spacecraft design, overall propulsion system efficiency is the efficiency with which the energy contained in a vehicle's fuel is converted into kinetic energy of the vehicle, to accelerate it, or to replace losses due to aerodynamic drag or gravity.

  9. K-epsilon turbulence model - Wikipedia

    en.wikipedia.org/wiki/K-epsilon_turbulence_model

    Unlike earlier turbulence models, k-ε model focuses on the mechanisms that affect the turbulent kinetic energy. The mixing length model lacks this kind of generality. [2] The underlying assumption of this model is that the turbulent viscosity is isotropic, in other words, the ratio between Reynolds stress and mean rate of deformations is the same in all directions.
