I want to write the following sentence in English:
Esto se debe al hecho de que las paredes provocan que el fluido se mueva mas facilmente alrededor de la particula ya que el espacio disponible entre la pared y la particula es muy pequeno para que el fluido fluya.
My attempt is:
That could be due to the wall which induces that the fluid move easier around the particle since the available space between the wall and the particles is very small and then the fluid cannot flow.
