Stability Analysis of Thermohaline Convection With a Time-Varying Shear Flow Using the Lyapunov Method
Kalin Kochnev, Chang Liu
This work demonstrates that the Lyapunov method can effectively identify the growth rate of a linear time-periodic system describing cold fresh water on top of hot salty water with…
Exact Coherent Structures of Sheared Double-Diffusive Convection
Van Duc Nguyen, Chang Liu
The interaction between shear and double-diffusive convection (DDC) in the diffusive regime (cold fresh water on top of hot salty water) plays an important role in the heat and mas…
Hypervelocity Impact Debris Cloud Trajectory-Planning based on Additive Manufactured Lattice Structures
Bilin Zheng, Xiao Kang, Xiaoyu Zhang +3
Space debris and micrometeoroid (MMOD) impacts pose a serious threat to the safe operation of spacecraft. However, traditional protective structures typically suffer from limitatio…
Influence of ambient temperature on cavitation bubble dynamics
Shaocong Pei, A-Man Zhang, Chang Liu +3
We investigate the influence of ambient temperature on the dynamics of spark-generated cavitation bubbles over a broad temperature range of 23 to 90. Increasing te…
Emergence of tension-compression asymmetry from a complete phase-field approach to brittle fracture
Chang Liu, Aditya Kumar
The classical variational approach to brittle fracture propagation does not distinguish between strain energy accumulation in tension versus compression and consequently results in…
