Effect of Mach number and plate thickness on the flow field and heat transfer characteristics of supersonic turbulent fl...
Conjugate heat transfer analysis of supersonic turbulent flow over a finite thickness flat plate is studied numerically. The flow field is modeled by employing the Favre averaged Navier–Stokes (FANS) equations. Turbulence is modeled with the Menter's shear-stress-transport (SST) k−ω model. The comparison of NCHT (non-conjugate heat transfer) and CH...
Bounds on internally heated convection with fixed boundary heat flux
We prove a new rigorous bound for the mean convective heat transport ⟨wT⟩, where w and T are the non-dimensional vertical velocity and temperature, in internally heated convection between an insulating lower boundary and an upper boundary with a fixed heat flux. The quantity ⟨wT⟩ is equal to half the ratio of convective to conductive vertical heat ...
Fabrication and electromechanical performance of carbon nanotube based conductive membrane and its application in real-t...
In this study, a flexible conductive membrane (CM) consisting of a network of carbon nanotubes is produced and the electromechanical behavior of this CM was studied experimentally and the gauge factor (GF) of CM was in the 8–8.25 range. Then, a multi-mode strain detection is carried out in composites using this CM sensor. The CM is embedded gradual...
Snap-buckling and failure studies on CFRP laminate with an embedded circular delamination under flexural loading
Carbon fiber reinforced polymer (CFRP) laminate having an embedded delamination may exhibit snap-buckling phenomenon under flexural loading, and its influence on the bending strength reduction and associated laminate failure mechanisms need to be understood for efficient structural design. In this paper, a multi-angle CFRP beam specimen with an emb...
Predicting collapse depth of paleocaves in carbonate reservoirs
Published in Carbonates and Evaporites
Paleocaves in carbonate reservoirs are the excellent oil and gas storage spaces in the field of petroleum exploration. Predicting the collapse depth of paleocaves in carbonate reservoirs has essential theoretical significance and applicable value for classifying of reservoir quality and delimiting lower depth of oil and gas exploration. Paleocaves ...
Western boundary layer nonlinear control of the oceanic gyres
This study examines the influence of flow nonlinearity in western boundary layers upon the turbulent wind-driven ocean gyres. Our analysis involves comparisons between large-scale circulation properties of the linear and nonlinear states, as well as a Lagrangian particle analysis of relevant flow features. We find that the so-called counter-rotatin...

High-order accurate direct numerical simulation of flow over a MTU-T161 low pressure turbine blade
Reynolds Averaged Navier-Stokes (RANS) simulations and wind tunnel testing have become the go-to tools for industrial design of Low-Pressure Turbine (LPT) blades. However, there is also an emerging interest in use of scale-resolving simulations, including Direct Numerical Simulations (DNS). These could generate insight and data to underpin developm...
