  • Falling film on flexible wall in the limit of weak viscoelasticity

    Peng, Jie   Zhang, Yang-Jun   Zhuge, Wei-Lin  

    The flow dynamics of an upper-convected-Maxwell (UCM) falling film down a flexible vertical wall is studied in the limit of weak viscoelasticity. A set of Benney-like weakly nonlinear equations for the film thickness and wall deflection, which is valid for small flow rate, is derived based on the long-wave theory. It shows that the unstable role of liquid viscoelasticity is equivalent to that of the flow inertia. A set of asymptotic evolution equations valid for moderate flow rate is obtained based on the integral theory. The linear instability property of the system is examined by using a normal-mode analysis. It shows that the liquid viscoelasticity acts to destabilize the falling film even for the flow with inertia being negligible. The nonlinear evolution equations for the moderate flow rate are solved numerically. The spatio-temporal evolutions of the liquid-air interface and flexible wall are examined. It is concluded that the liquid viscoelasticity plays a role to strengthen the dispersion of the initial imposed perturbation. It can promote the traveling speed of the solitary-like humps and suppress the front-running ripples at the same time. Both the wall damping and wall tension acts to suppress the fluctuations of the flexible wall. However, they play different roles in the evolution of the liquid-air interface.

  • Research on the Performance Influence of Second Adhesive to Friction Materials

    Peng, Jie   Liu, Yu Cheng   Yan, Zhi Feng   Wang, Bao Gang   Lin, Fu Dong   Zhuang, Jian   Ma, Yun Hai  

    The friction materials have many species and they are being used widely, but people have higher requests to friction materials with the development of technology. The friction materials of this experimental optimization formula have the advantages of suitable and stable friction coefficient under high temperature, low wear rate, good restoration characteristics. It can effectively reduce heat fade of friction and wear under high temperature braking. Friction and wear performance of friction materials with second adhesive is better than that of common preparation friction materials, it has higher friction coefficient and lower wear rate, it is determined by physical and chemical properties of tin and sulfur. While heating or wearing, the temperature of friction materials reach melting temperature of tin, it will become molten state, and sulfur has strong oxidability, on the one hand, tin and sulfur occurred chemical reaction which can generate sulfide, stannous (one sulfide tin),on the other hand, while the sulfur is being molten state, it will absorb some abrasive dust which be adsorbed and solidified to the friction surface, and formed abrasive dust membrane lead to the reduction of wear rate of friction materials.
