This work reports on the development of a Johnson noise electro-thermal (JET) technique to directly characterize the thermal conductivity of one-dimensional micro-/nanoscale materials. In this technique, the to-bemeasured micro-/nanoscale sample is connected between two electrodes and is subjected to steady-state Joule heating. The average temperature rise of the sample is evaluated by simultan...

The use of a synthetic jet as the flow control technique to modulate turbulent incompressible round was explored and assessed by numerical simulations. response characterised in terms statistics acoustic far-field. A quasi-Direct Numerical Simulation (qDNS) strategy used predict effects. Ffowcs-Williams Hawkings (FWH) analogy employed compute far-field response. An amplification effect instabil...

Three statistical jet noise prediction models are compared for a representative set of single-stream cases, which include cold and hot jets the Strategic Investment in Low-Carbon Engine Technology experiment at an acoustic Mach number 0.875 as well NASA small rig numbers 0.5 0.9. The implemented those proposed by Tam Auriault (Jet Mixing Noise from Fine-Scale Turbulence,” AIAA Journal, Vol. 37,...
