Computational efficiency is demonstrated by CFD simulation of the starting transients in ADDA solid rocket engines and in the SEATTLER solar mirror tower.
The code is exclusively directed to unsteady flow simulations in slender channels.
Still the 1D CFD approach is well justified in both applications – the RE and the ST –mainly due to the slender aspect of the channels in both ingredients.
The simulation of tower’s unsteady behaviour is based on the unsteady equations of the gas (air) flow.
