Thermal radiation-driven heat transfer in second-grade fluid over an oscillatory heated surface: analysis in fixed and moving reference frames

Oblique stagnation point flows have significant importance with their implementations in various disciplines including ocean waves, chemical vapor deposition, material coating, blood flow analysis, and engine cooling systems. By taking into account the significance of such flows, the current novel study communicates with the oblique stagnation point flow of a second-grade fluid corresponding to two distinct stationary and moving frames of reference. The thermal mechanism and magnetized flow nature of second-grade fluid in two dimensions are scrutinized through an oscillatory heated medium. In the problem formulation, special kinds of stream functions are introduced according to the moving frame and fixed frame. By taking into account these two special stream functions, the complete magnetized flow phenomenon and thermal process with the involvement of thermal radiation are briefly examined. Using the bvp4c solver in MATLAB, the dimensionless equations are analyzed, and the velocity and temperature profiles are examined graphically for both stationary and moving reference frames. This significant analysis yields an important result of increment of velocity regarding fixed frame of reference and improved fluid parameter.
