Experimental Investigation of NexGen and Gas Burner for FAA Fire Test
… were much more sensitive to a change in the fuel flow rate as opposed to a change in air flow rate. However, the fire test results on the samples were also sensitive to air flow rate. It is recommended that both fuel and air flow rate of NexGen burner should be regulated in future FAA fire tests. …

Reduction of excess fan power due to economizer damper pressure losses
An air conditioning system economizer, investigated in this thesis, consisted of three dampers, an outdoor air, a recirculation, and a discharge damper. The purpose of an economizer is to control the ratio of the outdoor air flow rate to the recirculation air flow rate. The dampers were opposed …

Flow Field and Soot Formation Characteristics in Swirl-stabilized Non-premixed Turbulent Flames
Soot formation and evolution in relation with the flow fields were investigated experimentally in turbulent swirl-stabilized non-premixed flames using three different fuels: methane, ethanol and aviation Jet A-1. The studied flames were confined and stabilized in a model gas turbine combustor with …

A fundamental study of two-dimensional room ventilation flows under isothermal and non-isothermal conditions
Understanding room air distribution is essential to the design of a ventilation system and the control of room thermal and air quality conditions. To investigate the various aspects of room air distribution, a Room Ventilation Simulator was developed with several unique features: an outer room with …
