ABSTRACT: The mathematical model of bioconvection flow of micropolar fluid through
a vertical surface containing nanoparticles and gyrotactic microorganisms is presented in this study. In the study, weak and
strong concentrations of microstructures are explored. In the energy and
concentration equations, the Catteneo-Christov
diffusion models are used to explain temperature and concentration diffusions with thermal and solutal
relaxation durations, respectively. The governing equations describing
the fluid flow are transformed and parameterized through similarity variables.
The approximate analytical solution is obtained by using Homotopy Analysis
Method (HAM). The impacts of relevant parameters on the various distributions are
investigated and illustrated. It is discovered that increasing the value of the
micropolar parameter results in an increase in the microrotation distribution
for strong concentrations of microstructures while decreasing the microrotation
distribution for weak concentrations of microstructures.
