Manuscript title: Bioconvection double stratification 3-D flow of Burgers nanofluid over a bidirectional stretched surface: Enhancing energy system performance

Abstract In recent years, the nanofluids are assumed to be most effective source of energy and reflect many applications in various industrial and engineering processes. With effective thermal properties, the nano-materials convey exclusive beneficial applications in heat exchanges, coolant processes, medical treatment, electronic cooling systems, energy production etc. The prime objective of current analysis is to scrutinize the three-dimensional double stratification flow of Burgers fluid containing microorganisms. The thermal radiation with nonlinear relations and heat absorption and generation applications are also endorsed. The modified forms of heat and mass diffusions are utilized to modify the analysis. The flow expressions for modeled problem are numerically evaluated by employing the shooting scheme. Physical features for various parameters against velocity of fluid, temperature distribution, volumetric concentration of nanoparticles and rescaled density of nanoparticles is deliberated with the help of several graphs. The observations reveal that heat and mass transfer mechanism decline with Deborah number. The concentration field rise up with concentration stratified Biot number while reduces with concentration relaxation constant. The presence of buoyancy parameters enhanced nanofluid temperature, concentration and microorganisms profiles. The obtained theoretical observation reveal applications in industrial, engineering and thermal processes which heat transfer involved. The claimed results are useful to improve the cooling and heating processes, energy generation, thermal devices, solar systems, manufacturing processes etc.
