Abstract: This work based on oscillation, fluctuation, periodic and transient analysis of heat and mass transmission of Casson nanofluid motion over a stretched surface with radiation, buoyancy force and entropy optimization. This problem is very useful in energy insulation, coating, energy conversion, climate, and ecological systems. The entropy generation and thermal radiations are applied to enhance the heat transmission of Casson nanomaterial. Periodic mathematical expressions are developed for this problem. Dimensionless variables, oscillatory-stokes formulation and primitive transformation are utilized to develop similarity in coding in FORTRAN language. Implicit finite difference methodology is applied for numerical outcomes in the presence of Gaussian elimination scheme. The computational outputs of velocity variation, energy and concentration graphs through different parameters are depicted. The steady as well as oscillatory form of skin friction and heat-mass transportation is depicted. The high magnitude in fluid velocity and temperature function is depicted with maximum entropy generation, Casson and radiation effects. The steady magnitude of heat and mass transportation is increased with Brownian motion and thermophoresis effects. The oscillation, amplitude and periodical waves in heat and mass transmission are increased with high Prandtl and Schmidt numbers.
