Significance of Bioconvective and Thermally Dissipation Flow of Viscoelastic Nanoparticles with Activation Energy Features: Novel Biofuels Significance

Abstract

The analysis of bioconvection flow nanofluids is the topic of concern in recent decades as it involves a variety of physical significance in biotechnology. Bioconvection has many applications in the interdisciplinary field of sciences such as in biomedical science, biofuel biotechnology, and enzyme-based biosensors, among others. The aim of the current work is to analyze the bioconvection phenomenon in the two-dimensional steady flow of viscoelastic nanofluid over a vertical surface. Here, the effects of activation energy, second-order slip, and nanoparticles zero mass flux conditions are considered to investigate the flow problem. Based on dimensionless variables, the governing partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) which are further solved numerically by using a built-in BVP4C approach in MATLAB software. Various controlling parameters like Hartman number, viscoelastic parameter, first and second-order slip factors, buoyancy ratio parameter, thermophoresis parameter, Brownian motion constant, bioconvection Lewis number and Peclet number are graphically illustrated for the distributions of velocity, temperature, concentration, and motile microorganism. Moreover, the variation of local Nusselt number, local Sherwood number, and motile density number are numerically investigated for the involved parameters.

“…They achieved that, hybrid nanoliquid displays a bigger heat transfer rate in contrast with the ordinary nanofluid. Waqas et al [7] revealed various uses related to the progression of nanoparticles within the sight of gyrotactic microbes. They utilized a secondgrade viscoelastic nanofluid pattern where the arithmetical arrangement has been determined by means of an implicit bvp4c calculation.…”

“…A flow model regarding bioconvection of Oldroyd-B nanoliquid in existence of activation energy generated by stretched cylinder was suggested by Tlili and co-workers [ 13 ]. Waqas et al [ 14 ] reported some biofuels application associated with the flow of nanoparticles in presence of gyrotactic microorganisms. They used a second grade viscoelastic nanofluid model where the numerical solution had been calculated via built-in bvp4c algorithm.…”

“…Waqas et al [29] examined the magnetohydrodynamics (MHD) flow of rate-type nanofluid in the presence of gyrotactic microorganisms with activation energy. Recently, Waqas et al [30] securitized the novel biofuel significance in viscoelastic nanofluid under the bioconvection process.…”
