説明

<p>We examine the effect of fluid acceleration on the decay characteristics of temporally and spatially decaying grid turbulence, where a spatially decaying turbulence is similar to a grid-generated turbulence. The derived forms from the governing equation of the turbulent kinetic energy show that there is a quantitative difference in the acceleration effects between the decaying turbulences. Using the observed forms, the negligible effect of the fluid acceleration in the present small wind tunnel is validated.</p><p></p>
