Effects.of hys.eres.s.of s.atic contact angle (Hs.A) and boundary s.ip on the hydrodynamics.of water s.riders

Acta Mechanica s.nica 2017年第1期33卷 40-61页

作者： J. Zheng B. s. Wang W. Q. Chen x. Y. Han C. F. Li J. Z. zhang K. P. Yu s.hool of Energy and Power Engineering Jiangsu UniversityZhenjiang 212013 China China s.ip s.ientific Res.arch Center Wuxi 200482 China s.hool of As.ronautics Harbin Institute of TechnologyHarbin 150001 China

It is.known that contact lines.keep relatively s.ill on s.lids.until s.atic contact angles.ex.eed an interval of hys.eres.s.of s.atic contact angle (Hs.A), and contact angles.keep changing as.contact lines.relatively s.ide on the s.lid. Here, the effects.of Hs.A and boundary s.ip were firs. dis.inguis.ed on the micro-curvature force (MCF) on the s.ta. Hence, the total MCF is.partitioned into s.atic and dynamic MCFs.corres.ondingly. The s.atic MCF was.found proportional to the Hs.A and related with the as.mmetry of the micro-menis.us.near the s.ta. The dynamic MCF, ex.rting on the relatively s.iding contact line, is.arous.d by the boundary s.ip. Bas.d on the Blake-Haynes.mechanis., the dynamic MCF was.proved important for water walking ins.cts.with legs.s.ower than the minimum wave s.eed . As.ins.cts.brus. the water by laterally s.inging legs.backwards. s.tae on the front s.de of the leg are pulled and the ones.on the back s.de are pus.ed to cooperatively propel bodies.forward. If they pierce the water s.rface by vertically s.inging legs.downwards. s.tae on the ups.de of the legs.are pulled, and the ones.on the downs.de are pus.ed to cooperatively obtain a jumping force. Bas.d on the dependency between the s.ip length and s.ear rate, the dynamic MCF was.found correlated with the leg s.eed U, as., where and are determined by the dimple depth. Dis.rete points.on this.curve could give fitted relations.as.(s.ter et al., J. Ex.. Biol. 200, 2523-2538, 1997). Finally, the ax.al torque on the inclined and partially s.bmerged s.ta was.found determined by the s.rface tens.on, contact angle, Hs.A, s.ta width, and tilt angle. The torque direction coincides.with the orientation of the s.iral grooves.of the s.ta, which encourages.us.to s.rmis. it is.a mechanical incentive for the formation of the s.iral morphology of the s.tae of water s.riders.

Us.ng Reddy’s.high-order s.ear theory for laminated plates.and Hamilton’s.principle, a nonlinear partial differential equation for the dynamics.of a deploying cantilevered piezoelectric laminated compos.te plate, under the combined action of aerodynamic load and piezoelectric ex.itation, is.introduced. Two-degree of freedom(DOF)nonlinear dynamic models.for the time-varying coefficients.des.ribing the trans.ers. vibration of the deploying laminate under the combined actions.of a firs.-order aerodynamic force and piezoelectric ex.itation were obtained by s.lecting a s.itable time-dependent modal function s.tis.ying the dis.lacement boundary conditions.and applying s.cond-order dis.retization us.ng the Galerkin method. Us.ng a numerical method, the time his.ory curves.of the deploying laminate were obtained, and its.nonlinear dynamic characteris.ics.including ex.ens.on s.eed and different piezoelectric ex.itations. were s.udied. The res.lts.s.gges. that the piezoelectric ex.itation has.a clear effect on the change of the nonlinear dynamic characteris.ics.of s.ch piezoelectric laminated compos.te plates. The nonlinear vibration of the deploying cantilevered laminate can be effectively s.ppres.ed by choos.ng a s.itable voltage and polarity.

Acta Mechanica s.lida s.nica 2018年第1期31卷 108-126页

In this.paper, the nonlinear trans.ent dynamic res.ons. of functionally graded material （FGM） s.ndwich doubly curved s.ell with homogenous.is.tropic material core and functionally graded face s.eet is.analyzed us.ng a new dis.lacement field on the bas.s.of Reddy＇s.third-order s.ear theory for the firs. time. The equivalent material properties.for the FGM face s.eet are as.umed to obey the rule of s.mple power law function in the thicknes. direction. Bas.d on Reddy＇s.theory of higher s.ear deformation, a new dis.lacement field is.developed by introducing the s.cant function into trans.ers. dis.lacement. Four coupled nonlinear differential equations.are obtained by applying Hamilton＇s.principle and Galerkin method. It is.as.umed that the FGM s.ndwich doubly curved s.ell is.s.bjected to s.ep loading, air-blas. loading, triangular loading, and s.nus.idal loading, res.ectively. On the bas.s.of double-precis.on variable- coefficient ordinary differential equation s.lver, a new program code in FORTRAN s.ftware is.developed to s.lve the nonlinear trans.ent dynamics.of the s.s.em. The influences.of core thicknes., volume fraction, core-to-face s.eet thicknes. ratio, width-to-thicknes. ratio and blas. type on the trans.ent res.ons. of the s.ell are dis.us.ed in detail through numerical s.mulation.

The points.of inters.ction between the bubble and body are treated, s.ecially in the numerical procedure. The aux.liary function method is.adopted to calculate the pres.ure on the body s.rface and in the flow field. The convergence s.udy is.undertaken to as.es. the developed numerical method and the computation code. s.me cas. s.udies.are undertaken in which the interactions.between the bubble/body and the incoming flow field are s.mulated.
