Odd Viscosity and Odd Elasticity

Michel Fruchart et al.

Summary: Elasticity refers to a material's ability to store energy, while viscosity refers to its tendency to dissipate energy. However, there are fluids and solids that display additional linear response coefficients known as odd viscosity and odd elasticity. This review discusses the continuum perspective of odd viscosity and odd elasticity, their rich phenomenology, and various systems that exhibit them. Additionally, it comments on the microscopic mechanisms underlying their emergence.

Role of odd viscosity on falling films over compliant substrates

Souradip Chattopadhyay et al.

Summary: We investigate the behavior of a thin liquid film flowing over a thin compliant substrate. Breaking the time-reversal symmetry introduces significant effects of the odd component of the Cauchy stress tensor, which have not been explored before. By employing the long-wave theory, we derive equations that couple the film's thickness and the compliant substrate, including considerations of inertia, damping effects, wall tension, and odd viscosity. Our linear stability analysis reveals that the compliant substrate destabilizes the system, while the odd viscosity significantly stabilizes it. Additionally, we employ a weakly nonlinear approach and derive the Kuramoto-Sivashinsky equation from the coupled long-wave equations. Remarkably, incorporating the odd viscosity tensor component can prevent chaotic behavior in compliant substrates under the weakly nonlinear limit. Numerical simulations demonstrate remarkable effects of odd viscosity on substrate deflection, and our numerical investigation of the coupled long-wave equations confirms the consistency of the linear and weakly nonlinear theories with the numerical results.

Shear imposed falling film with odd viscosity effects

Akshay S. Desai et al.

Summary: This study investigates the behavior of a thin liquid film flowing on an inclined plane under imposed shear stress. The breaking of the liquid's time-reversal symmetry is considered, and the odd part of the viscosity is used to describe the Navier-Stokes equation. A weighted residual model (WRM) is developed to study the interaction between the imposed shear and odd viscosity on flow dynamics. Through linear stability analysis, the critical Reynolds number (Rec) of the model is determined. The findings show that uphill shear stabilizes the flow, while downhill shear increases the instability, although mitigated by the presence of odd viscosity. An Orr-Sommerfeld (OS) type eigenvalue problem is also constructed for normal mode analysis, leading to the discovery of ReWRM = ReOS c in the longwave regime. The numerical simulations of the model align well with the linear stability analysis.

Role of odd viscosity in falling viscous fluid

Arghya Samanta

Summary: The aim of this study was to investigate the linear and nonlinear wave dynamics of a falling incompressible viscous fluid with the effect of odd viscosity. The study found that the odd viscosity coefficient can weaken surface and shear instabilities, as well as reduce the growth rate of the linear spatio-temporal response. Additionally, a nonlinear travelling wave solution of a two-equation model showed the attenuation of maximum amplitude and speed in the presence of an odd viscosity coefficient. This delayed the transition from a primary parallel flow with a flat surface to secondary flow generated through nonlinear wave interactions.

Long-wave instabilities of evaporating/condensing viscous film flowing down a wavy inclined wall: Interfacial phase change effect of uniform layers

Sanghasri Mukhopadhyay et al.

Summary: The interfacial phase change effect on a thin film flowing down an undulated wall has been investigated. The study reveals that the bottom steepness has a dual role in the stability of the film, increasing destabilizes in the downhill region, while increasing the bottom steepness stabilizes in the uphill region. It is also found that one subcritical region exists for evaporating film, while two subcritical unstable regions are found for condensate film. The rupture dynamics of the film are minimally affected by the bottom steepness, while the Kutateladze number significantly impacts the stability characteristic of the film flow.

Summary: We investigated the stability of a thin Newtonian liquid flowing on a heated slippery inclined plane. By constructing a mathematical model and conducting linear and nonlinear analyses, we concluded that the slippery substrate destabilizes the flow. Our numerical simulation results supported the analytical predictions and further examined the influence of small Biot numbers considering slip length and variable fluid properties.

Effect of odd viscosity on the stability of a falling thin film in presence of electromagnetic field

Juanxia Zhao et al.

Summary: In the presence of an electromagnetic field, the stability of a conductive thin liquid film flowing on a non-conductive inclined plate was studied, considering the effect of odd viscosity. The study revealed that odd viscosity and magnetic field stabilize the flow, while the electric field destabilizes it. Additionally, higher odd viscosity leads to a higher critical Reynolds number, and the stable region decreases while the unstable region remains almost unchanged as odd viscosity increases.

Thermocapillary instability in the presence of uniform normal electric field: effect of odd viscosity

Souradip Chattopadhyay

Summary: The study examines the stability and dynamics of a gravity-driven, viscous, Newtonian, thin liquid film with broken time-reversal symmetry draining down a nonuniformly heated inclined plane in the presence of a uniform normal electric field within the finite-amplitude regime. It is found that odd viscosity and electric field have different effects on flow dynamics, with odd viscosity providing stability while the electric field has a destabilizing tendency. Additionally, it is observed that thermocapillarity promotes instability in the flow.

Weakly viscoelastic film on a slippery slope

Souradip Chattopadhyay et al.

Summary: The study focuses on the stability of weakly viscoelastic film flowing down a slippery inclined plane, examining the interaction of bottom slip with viscoelastic parameters and other flow parameters. Two different methods were used to analyze the critical Reynolds numbers of the system, with the result indicating that in some cases, for small slip lengths, the first-order weighted residual method is more accurate in predicting instability thresholds than the first-order Benney equation model.
