Non-inertial Undulatory Locomotion Across Scales
… rely on waves of undulation for locomotion. In inertial regimes, organisms can leverage the forces generated by their body and the surrounding medium's inertia to enhance their locomotion (e.g., coast or glide). On the other hand, in non-inertial regimes self-propulsion is dominated by damping …

Physically-based animation of plant motions
… in this area is the incorporation of complicated non-inertial effects into plant motion. Previous works tend to either focus on quasistatic simulations - which by defnition assume the absence of non-inertial effects - or ignore secondary motion in their dynamics calculations altogether. Either of …

Aquatic gravity currents through emergent vegetation
… developed to categorize all flow conditions as inertial or non-inertial and the interface profile as linear, transitional, or non-linear, respectively, based on (a) the evolution of the velocity of the leading edge of the undercurrent and (b) the interface shape. Finally, the present model is …

Aerodynamic Modeling Using Computational Fluid Dynamics and Sensitivity Equations
… The method required the extension of standard (inertial) CFD formulations to general non-inertial reference frames. Generalized Navier-Stokes and Euler equations have been derived. The formulation is valid for all ranges of Mach numbers including transonic flow. The method was implemented …

Effects of pore-scale fluid flow on fluid-solid reactions in porous and fractured media
… important role. In porous and fractured media, inertial flows readily induce complex flow structures, such as recirculating flows. Such pore-scale flow structures can significantly alter fluid-solid reactions by controlling the pore-scale concentration fields. In addition, recent studies have …

Adaptive Rollover Control Algorithm Based on an Off-Road Tire Model
… vehicle responsible for generating all of the non-inertial forces to direct the motion of the vehicle. Tire force and moment behavior has been researched extensively and several accurate tire models exist. However, not much research has been performed on off-road tire models. This research …

Advances in Baffled and Railed Tube Ram Accelerator Operation and Modeling
… in experiments, and includes corrections for the non-inertial projectile reference frame. The new ram PFR model is able to predict the operational envelopes of the BTRA with remarkable accuracy and will now serve as a valuable tool in the development of future ram accelerator configurations.

The Effect of the Large Magellanic Cloud on the Dark Matter Halo of the Milky Way
… particles in the simulation are observed from a non-inertial reference frame relative to the outer halo leading to an appar-16 ent alignment in their orbital poles. The DM wake induced by the LMC changes the kinematics of particles in the Southern Hemisphere. Observations of satellites selected …

Plasma processes in pulsar environments
… radiation in the pulsar magnetosphere. The full nonlinear equations in cylindrical geometry for a streaming cold pair plasma are solved numerically, together with Maxwell's equations, using a Finite-Difference Time Domain method. Electrostatic oscillations are induced in a streaming plasma in the …

Direct numerical simulation of viscoplastic particulate flows
… can be difficult in practice due to its non-linear stress-strain behaviour. Complicating matters further, the cement slurries we are interested in contain suspensions of relatively large particles---micro beads---that are problematic for convential measurement tools such as concentric …

Modelling turbulence and transport of buoyant material in the ocean surface mixed layer
… direct numerical simulations (DNS), and model non-inertial, buoyant particles using a combination of buoyant tracers and three-dimensional Lagrangian particles. Surface cooling drives convection, and under this regime persistent convective vortices form which trap and accumulate buoyant …
