原始语种摘要: This paper presents a revised model for the titled ”Unsteady Mixed Nano-Bioconvection Flow in a Horizontal Channel with Its Upper Plate Expanding or Contracting” [18]. In this paper, the authors used a two phase model for the nanofluid presented in International Journal of Thermal Sciences 77 (2014), Mar., pp. 126-129 [15] in which the nanofluid particle volume at the wall is passively rather than actively controlled. Here, we observed that the boundary conditions are not satisfied in all curves of the nanoparticle volume fraction, ф, i. e. the curves do not match the boundary conditions presented in eq. (19). The second note is that all values of ф are positive which contradicts with the results presented in [15]. Since the equations are coupled then it can be said that not only the...
