The present study focuses on characteristics of a liquid sheet resulting from the oblique collision of two power-law fluid jets at low speed. Liquid expands radially from the impact point, forming a bay-leaf-shaped sheet bounded by a thicker rim. A theoretical model for two power-law impinging jets is established. Sheet velocity distribution is deduced through energy conservation during impingement; other sheet features are predicted by solving conservation equations for mass and momentum of the sheet rim where equivalent viscosity is proposed. The predicted sheet shape and rim diameter are compared to experiments, and they share good consistency. Based on the model, the effects of rheological parameters ( and ) on sheet characteristics, such as shape, velocity, and thickness distribution, are discussed.
