High-speed photography technology was used to investigate four kinds of shear-thinning Carbopol gel non-Newtonian power-law fluids with different Carbopol mass fractions by self-developed impinging jet system,the breakup pattern,spray cone angle and breakup length of liquid sheet of impinging jet were experimented and analyzed under different jet conditions.Results show that power-law fluids with different rheological properties have different breakup pattern,the higher viscosity means the more complex brea...
