Table 3 Parameters and correlations used to calculate reactor cross-sectional area.
Parameter | Symbol | Value | Equation | |
|---|---|---|---|---|
Oxidation step time | \(t_{{{\text{ox}}}}\) | 15 min | ||
Reduction step time | \(t_{{{\text{red}}}}\) | 15 min | ||
Cross-sectional area | \(A\) | 1.13 \({\text{ m}}^{2}\) | \(\frac{{\dot{V}_{{{\text{ox}}}} }}{{v_{0} }}\) | (6) |
Adiabatic index of CO2 | \(\kappa_{{{\text{CO}}_{2} }}\) | 1.23 | \(\frac{{c_{{\text{p}}} }}{{c_{{\text{v}}} }}\) | (7) |
Speed of sound in martian atmosphere (100% CO2) | \(c_{{{\text{CO}}_{2} }}\) | 221 m/s | \(\sqrt {\kappa_{{{\text{CO}}_{2} }} \cdot \frac{{R \cdot T_{{\text{M}}} }}{{M_{{{\text{CO}}_{2} }} }}}\) | (8) |
Maximum flow velocity | \(v_{0}\) | 55 m/s | \(M \cdot c_{{CO_{2} }}\) | (9) |
