Convective nonlinear thermally developed flow of thixotropic nanoliquid configured by Riga surface with gyrotactic microorganism and activation energy: A bio-technology and thermal extrusion model

The thermal performances of base materials with thermal radiation, variable heat transportation features and activation energy are quite progressive which allow many industrial, engineering and technological applications. The scientists are still focusing to discover the cheap and friendly environment energy resources. On this end, the utilization of nanoparticles as a energy resource is intended much attention of researcher in recent decade. Moreover, the bioconvection of nano-materials is also a fundamental approach to improve the nanoparticles stability and many bio-technology applications like enzymes, petroleum engineering application, bio-fuels, biosensors and many more. Present analysis aim to discover the complex rheological characteristics of thixotropic nanofluid in presence of gyrotactic microorganisms over a Riga surface. The most fascinating features of nonlinear thermal radiation and activation energy are also carried out to improve the heat and mass transportation process. The formulated flow problem is preceded by using convective Nield boundary conditions. After successfully attaining the dimensionless form of formulated set of flow equations, a famous shooting numerical scheme is followed with appliances of MATLAB computational software. The involved flow parameters significance is graphically underline with well justified physical consequences. All physical quantities determining the heat, mass and microorganisms transportations are comprehensively studied via graphs and tables. The key observations revealed from this novel numerical continuation lead to many thermal engineering and solar energy systems applications, energy resources and consumptions, enzymes, bio-sensors and bio-technology.
