Project 48: Effect of different surrogates on combustion phasing of Gasoline Direct Injection Engine (GDI) operated under partially and perfectly homogeneous conditions.

Suitable Majors

Chemical Engineering, Chemistry, Mechanical Engineering

Research Area

​Combustion

Internship Description

Real fuels (e.g. gasoline, diesel and jet fuels) consist of a wide range of components which pose a real challenge to chemical kinetics modelers. Surrogate fuels present an efficient and prevalent methodology to model complex real fuels. Surrogate fuels are mixtures of a smaller number of hydrocarbons to mimic the chemical and physical properties of real fuels with affordable computational costs. The surrogate becomes more complicated when more target properties are included in the formulation process. Hence, careful considerations need to be made when selecting appropriate surrogate components and target properties.


3D engine simulations will be conducted using Converge software package for different surrogates incorporating reduced kinetic models. For homogeneous operations; 0D simulations will be also conducted with detailed kinetic models using Chemkin-pro software. The results from both will be compared and discussed.


Temperature and equivalence ratio contours will be generated from the results using Paraview software. In addition, 3D videos for engine simulations will be produced.

Prerequisites

The student should have interest and/or expertise in one of the following areas: computer programming, life cycle assessment, reaction engineering, chemical thermodynamics, quantum chemistry, and combustion simulations.

Deliverables/Expectations

-       Understanding the effect of different surrogates on ignition.
-       Understanding the effect of start of injection on ignition.
-       Insightful consideration of surrogates suitable for specific engine operation mode.
