Variations of axial and radial temperature inside the HLTP for microalgae cell growth

Abstract

The demand for microalgae-based biofuel has been attracted globally due to huge fuel demand and the global warming crisis. In this study, we simulated the axial and radial temperatures for microalgae cell growth. The computational domain is considered a horizontal loop tubular photobioreactor (HLTP) due to its high productivity. However, due to proper temperature variations, the growth is obtained as expected. We found that for proper cell growth, the standard temperature range is 293K–308K. From our simulation, we observed that the maximum temperature is near 312K through the axial direction and the maximum temperature is near 314K through the radial direction.
