WebIt has been observed that both the Grashof number and the sinusoidal even and odd frequency have a significant influence on the streamlines and isotherms inside the cavity. The heat transfer rate enhanced by 90% from the heated surface as the Grashof number ( Gr) increased from 10 5 to 10 7 at sinusoidal frequency N = 1 and τ = 1. Keywords: WebThe Grashof number is defined as (8.54)Gr=gβΔTz3ν3where β is the air expansion coefficient, ΔT is the temperature difference, and z is the length of the path followed by the airstream generated by ΔT.
