Comparative evaluation of different heat transfer correlations on a single curved-cylinder spark ignition crank-rocker engine

open access: yesAlexandria Engineering Journal, 2021
Crank-rocker (CR) engine is a new kind of combustion engine that has a curved-cylinder combustion chamber. To enhance CR engine development and performance, high accuracy modeling which accurately predicts combustion characteristics is required.

On the Application of Proper Orthogonal Decomposition (POD) for In-Cylinder Flow Analysis

open access: yesEnergies, 2018
Proper orthogonal decomposition (POD) is a coherent structure identification technique based on either measured or computed data sets. Recently, POD has been adopted for the analysis of the in-cylinder flows inside internal combustion engines.
