Flow Visualization Around a Non - Circular Tube

The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...

Turbulent Flow Visualization in Computational and Experimental Hydraulics

Many practical problems in open channel hydraulics that were traditionally investigated in hydraulic model experiments, are nowadays being solved by using computational fluid dynamics. However, in order to interpret computational results, there is a clear preference among scientist and engineers for visualization in analogy with experimental techniques. One such technique, particle tracing, ena...

Computational Visualization of Physics and Topology in Unsteady Flow

Vector fields play an important role in many areas in research and engineering. This thesis originated in the context of a project with two industry partners active in turbo-machinery and is hence oriented toward this area. Nevertheless, its first part addresses generic fluid flows whereas its second part is even more universal: its subject are vector fields in general. Design of turbo-machiner...

Design of Air Distribution System for Operation Theatre Using Flow Visualization Techniques to Improve Flow Characteristics

Operation Theatre (OT) is the most important area where precise controlled on indoor air quality is required because it is directly related to patient health and its recovery period. This work aims to study and visualize the airflow distribution of conventional flat air diffuser ventilation system and newly designed angular air ventilation system in OT. Angular Air Distribution (AAD) system is ...
