Dr. Olayiwola's research interests include heat transfer, energy systems and fluid mechanics, separation process, rheology of complex fluids, computational fluid dynamics and pulse systems.
The use of low frequency oscillations f < 200 Hz to enhance process performance permits oscillation effects mainly dominated by oscillation velocity. In addition, it is possible to maintain uniform oscillation amplitude A even within long channels. In smooth channel and with oscillating flow, the velocity profile is modified such that maximum velocity occurs near the channel walls and not at the centreline as often found with steady laminar flow in pipes. The net result is substantial increase in the wall shear stress. In the presence of inserts perpendicular to the main flow, intense local mixing, boundary layer disturbance and significant increase in the transport processes across the exchange surfaces occur. The research focuses on the development of basis for increased transport coefficients in transfer systems.
Within the INTEK project (http://www.bmbf.de/en/) extensive examinations are being performed regarding heat transfer and mixing performance in scraped surface heat exchangers. Further examinations cover the dispersing process of low viscous liquid in high viscous systems using dynamic mixers.
