ESR2: Vikrant Mahesh

vikranmaheshBorn in the south of India, in a place called Bangalore known as the IT capital of India, Vikrant had a deep sense of curiosity towards thermophysical experimental investigation with respect to automotive applications. This led him to pursue his Master in Automotive Engineering at the University of Brighton and University of Sussex in UK. Working under the supervision of Dr Steven Begg at Sir Harry Ricardo Labs gave him the depth of understanding required to appreciate the thermophysical properties and aeromechanical behaviour involved engine combustion process. His work led to the development of the swirl flow device that is still used today to measure in-cylinder flows on a flow rig. Presently, he has been recruited as a research member in the IPPAD project at Friedrich-Alexander University Erlangen-Nürnberg and works at the “Engine Combustion Process” research group under the supervision of Prof. Dr.-Ing. Michael Wensing.

His topic in this project titled “Primary atomization of fuels with additives under trans-critical and supercritical conditions” in which he will work on the experimental investigation of the primary atomization region to understand the influence of supercritical parameters on diesel behaviour. High energy x-rays and high speed/magnification imaging techniques will be used to characterise the morphology of the liquid forming and atomising close to the nozzle exit. These investigations will be performed in a Constant Volume Chamber under trans-critical and supercritical conditions for non-additised fuels and fuels enriched with additives.

ESR6: Carlos Rodriguez

carlosrodriguezBorn in Leon, a city in the north of Spain, he moved to Valencia to study a master’s level-double degree in Aerospace Engineering at the Polytechnic University of Valencia after completing a three years degree in Aerospace Engineering at the University of Leon. In the last year, he decided to move to Cranfield University as part of an Erasmus programme to do a MSc in Computational Fluid Dynamics. His degrees have equipped him with knowledge across the computational fluid dynamics field, ranging from programming complex numerical schemes to an advanced knowledge of commercial software. His strong technical and problem solving abilities enable him to work flexibly in a variety of areas. He has been recruited research member of the IPPAD Project at City University London.

His project is titled “Direct numerical simulation of fuel atomisation at supercritical conditions”, in which he will develop a numerical methodology applicable for injection of fuels under supercritical conditions. The computational model will be able to determine if the fuel enters a supercritical state that allows it to mix with noncondensable gases (N2 + O2) or whether the fuel droplet has to vaporize before mixing. Advanced algorithms and dynamic grid refinement methods will be used to suppress numerical diffusion of the gas/vapour-liquid interface.

songzhiyangSongzhi Yang, coming from China, she has shown strong interest in engineering since she was a little girl, which has made her successfully enroll in the ‘Advanced Engineering Talents’ program in Central South University for undergraduate study. Four years later, by excellent academic performance, she was recommended to Automotive Engineering department in Tongji University for graduate study. The main research work she has done was to reduce the aerodynamics drag of automotive by CFD simulation. Through participating in a series of projects involving CFD modelling, she was deeply intrigued by its high efficiency and accuracy which has stimulated her to learn more about simulation. Now being a member of IPPAD program has given her a good opportunity to explore further in CFD field.

Her Ph.D project is titled ‘Diesel injection modelling in subcritical and supercritical condition’, in which she will implement the real EoS into the CFD code and develop new CFD code aimed to simulate the injection in subcritical and supercritical condition simultaneously.
