Modelling diesel spray evaporation using a noniterative implicit solution scheme

Diesel Spray Modelling: A Review

An overview is provided of the current state of the art in Diesel spray prediction. The modelling of the key physical processes is discussed and the impact on prediction accuracy is illustrated by way of examples. The overall conclusions are that comprehensive methodology of useful accuracy now exists; but further theoretical and experimental research is needed, especially in respect of atomisa...

Fuzzy Logic and Neuro-fuzzy Modelling of Diesel Spray Penetration

This paper describes a comparative evaluation of two fuzzy-derived techniques for modelling fuel spray penetration in the cylinders of a diesel internal combustion engine. The first model is implemented using conventional fuzzy-based paradigm, where human expertise and operator knowledge were used to select the parameters for the system. The second model used an adaptive neuro-fuzzy inference s...

A General Solution for Implicit Time Stepping Scheme in Rate-dependant Plasticity

In this paper the derivation of the second differentiation of a general yield surface implicit time stepping method along with its consistent elastic-plastic modulus is studied. Moreover, the explicit, trapezoidal implicit and fully implicit time stepping schemes are compared in rate-dependant plasticity. It is shown that implementing fully implicit time stepping scheme in rate-dependant plasti...

Fuzzy logic and neuro-fuzzy modelling of diesel spray penetration: A comparative study

The aim of this study was to demonstrate the effectiveness of an adaptive neuro-fuzzy inference system (ANFIS) for the prediction of diesel spray penetration length in the cylinder of a diesel internal combustion engine. The technique involved extraction of necessary representative features from a collection of raw image data. A comparative evaluation of two fuzzy-derived techniques for modelli...
