Multiscale simulation of rarefied gas dynamics via direct intermittent GSIS-DSMC coupling
Advances in AerodynamicsThe general synthetic iterative scheme (GSIS) has proven its efficacy in modeling rarefied gas dynamics, where the steady-state solutions are obtained after dozens of iterations of the Boltzmann equation, with minimal numerical dissipation even using ...

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys
Advanced Engineering Materials, EarlyView.An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Multilayer Self‐Limiting Electrospray Deposition via Stepped Voltage Bias
Advanced Engineering Materials, EarlyView.Self‐limiting electrospray deposition (SLED) uses a high voltage to generate and deposit a charged payload on a target surface. The coating retains its charge, repelling newly arriving material. SLED thickness can be decreased by applying a secondary bias to the target.

Separate modeling of trace species in hypersonic rarefied gas flows [PDF]
, 2014 Trace species in hypersonic rarefied gas flows play an important role in predicting electromagnetic phenomena.A typical example appeared in the RAM-C Ⅱ flight test:the mole fraction of trace species were several orders lower than those of primary species

Simulation of hypersonic rarefied flows with the immersed‐boundary method [PDF]
, 2011 This paper provides a validation of an immersed boundary method for computing hypersonic rarefied gas flows. The method is based on the solution of the Navier‐Stokes equation and is validated versus numerical results obtained by the DSMC approach.
