Profile Summary

Investigations into the thermal-hydraulic stability of advanced power plants such as those with Supercritical-CO2 Closed Brayton Cycles and Direct-Steam Generation (DSG). Development and testing of control strategies in applications with fluctuating heat-source and cooling conditions (e.g. air-cooled concentrated solar thermal (CST) power plants). Investigation of control strategies and stability envelopes for systems with inherent instabilities including two-phase flow induced and non-uniform parallel-channel flow systems such as for DSG in solar thermal plants. MODELICA® for power plant dynamic simulation and control strategy development. Specification, design, construction, commissioning, and operation of high-pressure and advanced power cycles. Development and integration of safety, sensing, control, and data acquisition systems. FEA based structural analysis and modification of coal mining draglines, shovels, stackers, reclaimers to Australian standards Flow visualisation, CFD of complex flows on delta-wing aircraft
