“…Much research considers only the linear first order approximations while others consider higher order approximation (Lund 1965, Lund and Thomsen 1978, Qiu and Tieu 1996, Miura et al 2017. There are different methods to obtain the bearing coefficients,such as, experimental (Tiwari et al 2004, Mao et al 2016analytical (Chasalevris andSfyris, Wang andKhonsari 2006, Miraskari et al 2018a), finite difference method(FDM) (Gero and McC. Ettles 1986, Qiu and Tieu 1995, Goodwin et al 1997, finite element method (FEM) (Wada et al 1971, Mourelatos 1985, Arregui and Vázquez 2001, Nair and Nair 2004, Awasthi et al 2006, Hili et al 2010 , mesh less method with radial basis (MMRB) (Nicoletti 2013) and computational fluid dynamics (CFD) (Gao et al 2014, Zhang et al 2015.…”
