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.

WebThe residual errors for SWCNTs/MWCNTs-Water are presented in Table 2. The influence of the unsteadiness constraint S, Reynolds number Re and Grashof number G r versus the local skin friction are scrutinized in Table 3. The large values of S and Re raises the skin friction coefficient f ″ (1). In fact, the larger values of these parameters ... In fluid mechanics (especially fluid thermodynamics), the Grashof number (Gr, after Franz Grashof ) is a dimensionless number which approximates the ratio of the buoyancy to viscous forces acting on a fluid. It frequently arises in the study of situations involving natural convection and is analogous to the … See more Heat transfer Free convection is caused by a change in density of a fluid due to a temperature change or gradient. Usually the density decreases due to an increase in temperature and … See more The first step to deriving the Grashof number is manipulating the volume expansion coefficient, $${\displaystyle \mathrm {\beta } }$$ as follows.
