Research

Dr Yan has research interests in experimental fluid mechanics and heat transfer using liquid crystal thermography, laser based diagnostics and high speed imaging techniques. The experimental techniques have been applied to study: boiling heat transfer, heat transfer enhancement by sliding bubbles, heat transfer in pre-swirl cooling systems, fuel spray characterisation, fuel mixture in gasoline direct injection engines and piston ring lubrication in automotive engines.
