Mixed bioconvection stagnation point flow towards a vertical plate in alumina-copper/water

Purpose: According to the previous research, bioconvection has been recognized as an important mechanism in current engineering and environmental systems. For example, researchers exploit this mechanism in modern green bioengineering to develop environmentally friendly fuels, fuel cells and photosyn...
