Bubble moving along an inclined surface is a common phenomenon in industry.A single bubble rising along an inclined adiabatic surface was simulated with the lattice Boltzmann method(LBM).The influences of initial bubble diameter

inclined angle and Eotvos number on bubble deformation and the vertical distance between its centroid and the surface

were studied.Under the condition of fixed initial bubble diameter

the relationships between bubble terminal velocity

inclined angle and Eotvos number were also investigated.The simulation revealed that the asymmetry of bubble became significant with the increasing of inclined angle.During the rising process

the trajectory of bubble's centroid remained parallel to the surface.When the inclined angle was greater than 45°

the vertical distance between its centroid and the surface increased with the Eotvos number

while when it was less than 45°

the variation was the opposite.Besides

the bubble's terminal velocity increased with increasing inclined angle and Eotvos number for the same initial diameter.
