Recent studies on the performance of solar distillers using nano Al2O3
| Ref | Nature | Solar still type | Material used | Results |
|---|---|---|---|---|
| Kabeel et al. (2014) | Experimental | Single slope | Al2O3 |
With the external condenser, the solar still water productivity increased by about 116% Water cost 0.041 $/L |
| Sahota and Tiwari (2016) | Theoretical | Double slope | 0.12% Al2O3 concentration | The enhancement of yield has been found to be 12.2% |
| Chaichan and Kazem (2018) | Experimental | Single slope | Paraffin wax with a nano-Al2O3 | Distillate yield improved by 60.53% |
| Modi et al. (2021) | Experimental | Single-basin dual-slope | 0.1% Al2O3 | Use of Al2O3 improved the yield by 28.53% |
| Kabeel et al. (2017a) | Numerical | Single slope | 0.2% Al2O3 and 0.2% Cu2O | The daily efficiency improved by 73.85% and 84.16% for Al2O3 and Cu2O nanoparticles, respectively |
| Shanmugan et al. (2018) | Experimental + Theoretical | Single slope | Al2O3 | The daily yield was 7.460 kg/m2 in summer and 4.120 kg/m2 in winter |
