主 题：Cavity flow natural convection bio-thermal convection Coiflet wavelet homotopy analysis method
摘 要：In this paper,the natural convection of a complex fluid that contains both nanoparticles and gyrotactic microorganisms in a heated square cavity is *** Buongiorno model is applied to descirbe the nanofluid *** the top and bottom horizontal walls of the cavity are adiabatic,and there is a temperature difference between the left and right vertical *** non-dimensional governing equations are obtained when the stream-vorticity formulation of function is used,which are solved by the recently developed robust Coiflet wavelet homotopy analysis method.A rigid verification for the solver is ***,the effects of various physics parameters including the Rayleigh number,the buoyancy ratio parameter,the bioconvection Rayleigh number,the Prandtl number,the Brownian motion parameter,the thermophoresis parameter,the heat generation parameter,the Lewis number,the bioconvection Peclet number and the Schmidt number on this complicated natural convection are *** is known that natural convection is closely related to our daily life owing to its wide existence in nature and engineering *** believe that our work will make a significant contribution to a better understanding of the natural convection of a complex fluid in a cavity with suspensions of both inorganic nanoparticles and organic microorganisms.
