Dr. Jung graduated with a B.Eng. in Mechanical Engineering from Chonbuk National University, South Korea. He then worked as a maintenance officer (lieutenant) at the Republic of Korea Air Force (a special case of compulsory military service) and as a plant engineer for Panasia Paper Korea – Norske Skog and Abitibi Consolidated (the 3rd largest mill in the world at that time and currently called as the Jeonju Paper Corporation). He permanently moved to New Zealand in the early 2000s and earned his Ph.D. in Mechanical Engineering from the University of Canterbury. Prior to his current academic position, he worked as a Postdoctoral researcher at Canterbury for over three years in the area of organic Rankine cycle (ORC) systems for conversion of low-temperature geothermal fluids and low-grade industrial waste heat into electricity under two main research projects. This was in collaboration with a number of industrial partners, and was supported by the New Zealand Heavy Engineering Research Association funded by the Ministry for Science & Innovation. His research mainly focuses on the modelling & design of thermal energy systems, notably, Pentgeneration systems running with renewable energy. He is an expert in the numerical modelling of the organic Rankine cycle, ejector cooling systems, thermal desalination, turbines, centrifugal pumps, heat exchangers, and piping systems. He is a Chartered Engineer (CEng MIMechE). He joined Curtin University, Malaysia Campus in 2015.

Postgraduate Research Opportunities

Project 1: Design and feasibility study of a small scale combined heat and power plant based on oil palm waste-fired organic Rankine cycle for remote villages

Degree: Masters or Ph.D.

Project Description:

Based on the research question of what new technology can be developed that creates export opportunity for Malaysia business by improving the quality of lives of residents in remote villages and islands where they do not have access to main grid electricity, and also by reducing cost of power generation, this research represents the first stage (a design phase) of a two stage project where we will ultimately carry out the construction, operation and evaluation of a small scale combined heat and power (CHP) plant. Student is given an overseas internship opportunity in NZ, Korea, or Australia during the study period.

Funding Arrangements:

Funding is now being sought from MOSTI but has not yet materialized.


Project 2: Assessment of the suitability of sewage sludge as a fuel source for organic Rankine cycle power plants

Degree: Masters or Ph.D.

Project Description:

Sewage (or wastewater) is waste from all sinks, toilets, laundries, kitchens and bathrooms. This water includes sludge or heavy organic matter which is scraped in sewage treatment plants and pumped to digesters for treatment. During this sludge treatment process ‘helpful’ bacteria break down the sludge to form biosolids. The biosolids are in the form of damp cake after passing through a machine that squeezes water out. Biosolids or treated sludge can be dried using heat. In this study we will investigate the suitability of the treated sludge as a fuel source for organic Rankine cycle power plants.


Funding will be sought from FRGS.


Project 3: Design of an automatic oil palm wastes furnace for small size organic Rankine cycle power plants

Degree: Masters or Ph.D.

Project Description:

In the biomass-based ORC system, biomass is burned in a furnace and then the heat released is transferred to thermal fluid (oil or water) traveling through boiler. The high temperature thermal fluid evaporates working fluid in evaporator and then the pressurised fluid vapour passes through expander, expanding and turning the expander connected to a generator. In this research programme we will design a novel furnace combusting oil palm wastes, such as empty fruit bunches, fibre, shell, and palm kernel, by focusing on minimising emissions and avoiding ash deposition or clog in the boiler.


Funding will be sought from FRGS.


Project 4: CFD & FEA of a radial inflow turbine with refrigerant for small scale organic Rankine cycle systems

Degree: Masters or Ph.D.

Project Description:

Radial inflow turbine is a potential candidate for ORCs. It can achieve high expansion ratio with low flow rate of working fluid. It can also maintain high efficiency at off-design conditions with the use of variable geometry stator.  In this study, we will make use of an in-house developed simulation model for the meanline design of a radial turbine and then CFD and FEA will be performed using ANSYS Turbosystem for the detailed design of rotor blades, nozzle vanes, and volute. The Student is given an overseas internship opportunity in NZ, Korea, or Australia during the study period.


Funding will be sought from FRGS.


Current Postgraduate Supervision

Ph.D. Students:

  • Tommy Ting Siew Fock

Project: Modelling and design of a rotary vane expander for oil palm waste-fired organic Rankine cycle power plant (Principal supervisor)

Project Description:

The importance of renewable energy in the generation of electricity cannot be overstated when considering the rising cost and environmental impacts of fossil fuels. ORC (organic Rankine cycle) system is a proven technology that can be used to convert renewable energy, such as low-temperature geothermal fluids, low-grade waste heat, biomass, and solar thermal energy, into electricity thanks to the use of working fluids with low boiling points, such as pentane, butane, R245fa, and R365mfc. Compared with the conventional steam power plants, the ORC system operates at incomparably low boiling temperatures and low pressures and thus the system is simple and easy to operate. The key component of the ORC is expander which critically influences the system efficiency. In this research project, we will develop a computer simulation model of rotary vane expander.
