Zhu, S., Vijayalakshmi, S., Ngwaka, U., Roy, S., Williams, R., Smallbone, A., & Roskilly, A. P. (2024, September). A preliminary experimental study on a free-piston engine generator prototype. Presented at Energy Proceedings, Niigata, Japan

As an emerging micro- or small-scale energy conversion technology, free-piston engine generator (FPEG) features the advantages of high efficiency, high volumetric power density, and multi-fuel adaptability potential. To solve the issues that the prev... Read More about A preliminary experimental study on a free-piston engine generator prototype.

Entropy generation rate optimisation for profiled endwall design for axial turbines (2024)
Presentation / Conference Contribution
Martinez-Castro, P. A., Williams, R. J., & Ingram, G. L. (2024, September). Entropy generation rate optimisation for profiled endwall design for axial turbines. Presented at GPPS Chania 2024, Chania

This paper investigates the formulation of the optimal objective function for aerodynamic design of turbomachinery using genetic algorithms (GA) supported by Computational Fluid Dynamics (CFD). The aim is to outline entropy generation rate minimisati... Read More about Entropy generation rate optimisation for profiled endwall design for axial turbines.
