This study was carried out to investigate effects of acoustic and thermofluid performance of a RanqueHilsch
Vortex Tube (RHVT) with different numbers of swirl generator nozzles. The number of nozzle
used in the experiment was 1, 2, 3, 4, 5 and 6 nozzle(s), respectively. Sound signal produced by the device
was recorded using two microphones located at hot side and cold side of the tube. The sound signal
was transformed using Fast-Fourier Transform (FFT) to obtain the frequency representation. Then, the
frequencies produced were related to its themofluid performance of each configuration.
The blended wing body (BWB) aircraft has a unique design. The main body and wing of BWB are
merged to increase the lift force on the aircraft. However, BWB has poor stability arising from the absence of the tail. Hence, a small horizontal stabilizer called as canard has been incorporated in front of the main wing to improve BWB’s stability. Computational Fluid Dynamics (CFD) simulations conductedm to obtain the aerodynamics parameters of the BWB i.e. lift, drag and moment coefficients, showed that overall, the canard is beneficial to the BWB aerodynamics performance.
