My research field is heat transfer investigation using liquid crystal thermography in, e.g., rib-roughened rectangular ducts. The flow rates have been varied to provide Reynolds numbers between 1000 and 6000, covering the range from laminar to low turbulent flow. The ducts with parallel ribs, V-shaped ribs pointing downstream and upstream have been tested, and local heat transfer coefficients are obtained. The average Nusselt number is evaluated based on local data, and normalized to smooth values to study the enhancement factor.
Future work includes impinging multiple jets.
