The effects of swirl and tumble on combustion in spark-ignition engines
P.G. Hill,D. Zhang +1 more
TL;DR: A review of rotating flow in premixed spark-ignition engines and its effects on turbulence generation and flame propagation can be found in this article, where the mean velocity and turbulence fields associated with these rotational motions are reviewed, as well as the mechanisms for decay, generation, transport and enhancement of in-cylinder turbulence.

In-cylinder fluid flow, turbulence and spray models—A review
Syed Ameer Basha,K. Raja Gopal +1 more
TL;DR: A literature review of use of computational fluid dynamics (CFD) codes to model the in-cylinder fluid flow, turbulence and spray characteristics is presented in this paper, based on the reports of about 60 scientists, who published their results between 1978 and 2008.

Measurements and predictions of the precombustion fluid motion and combustion rates in a spark ignition engine
TL;DR: In this paper, the mean velocity and turbulence intensity measured in a motored research engine were used to predict the decay of turbulence at a point in the flow after the production phase is completed.

Progress in the development of a Reynolds-stress turbulence closure
TL;DR: In this article, the authors developed a model of turbulence in which the Reynolds stresses are determined from the solution of transport equations for these variables and for the turbulence energy dissipation rate E. Particular attention is given to the approximation of the pressure-strain correlations; the forms adopted appear to give reasonably satisfactory partitioning of the stresses both near walls and in free shear flows.

The method of weighted residuals and variational principles
TL;DR: In this article, the method of Weighted Residuals is used to solve boundary-value problems in heat and mass transfer problems, and convergence and error bounds are established.
Journal ArticleDOI
The velocity and temperature distribution in one-dimensional flow with turbulence augmentation and pressure gradient
TL;DR: In this article, the Kolmogorov-Prandtl turbulence energy hypothesis is formulated in a way which is valid for the laminar sublayer as well as the fully turbulent region of a one-dimensional flow.

Experimental and theoretical investigation of turbulent burning model for internal combustion engines
Norman C. Blizard,James C. Keck +1 more
TL;DR: In this paper, a model for describing turbulent flame propagation in internal combustion engines is presented, and an approximate analytic method for determining the equilibrium state of the burned gases is also presented.
