About Professor David Fletcher

I am an Adjunct Professor who works closely with experimentalists and industrial companies to study problems involving flow, heat transfer and combustion. I have a passion for research that has kept me associated me with Sydney University for over 15 years. Using state of the art software and computing facilities I perform research that has a major impact on industrial process design and aids the development of new environmentally-friendly technologies. The computer modelling that can now be performed was unimaginable even a few years ago so there are thousands of interesting problems waiting for you.

Computer modelling to understand, design and improve chemical processes and equipment involving flow, heat transfer and chemical reaction.
