      abstract     = {Smoothed dissipative particle dynamics (SDPD) combines two
                      popular mesoscopic techniques, the smoothed particle
                      hydrodynamics and dissipative particle dynamics (DPD)
                      methods, and can be considered as an improved dissipative
                      particle dynamics approach. Despite several advantages of
                      the SDPD method over the conventional DPD model, the
                      original formulation of SDPD by Español and Revenga (2003)
                      [9], lacks angular momentum conservation, leading to
                      unphysical results for problems where the conservation of
                      angular momentum is essential. To overcome this limitation,
                      we extend the SDPD method by introducing a particle spin
                      variable such that local and global angular momentum
                      conservation is restored. The new SDPD formulation (SDPD+a)
                      is directly derived from the Navier–Stokes equation for
                      fluids with spin, while thermal fluctuations are
                      incorporated similarly to the DPD method. We test the new
                      SDPD method and demonstrate that it properly reproduces
                      fluid transport coefficients. Also, SDPD with angular
                      momentum conservation is validated using two problems: (i)
                      the Taylor–Couette flow with two immiscible fluids and
                      (ii) a tank-treading vesicle in shear flow with a viscosity
                      contrast between inner and outer fluids. For both problems,
                      the new SDPD method leads to simulation predictions in
                      agreement with the corresponding analytical theories, while
                      the original SDPD method fails to capture properly physical
                      characteristics of the systems due to violation of angular
                      momentum conservation. In conclusion, the extended SDPD
                      method with angular momentum conservation provides a new
                      approach to tackle fluid problems such as multiphase flows
                      and vesicle/cell suspensions, where the conservation of
                      angular momentum is essential.},
