A low‐energy approach to processing large‐scale airflow

A simplified solar updraft device adapted from the Trombe wall concept was built to process large-scale airflow using only energy. The performances were systematically studied experimental measurements and numerical models, with focus of investigating whether this can generate enough under low intensities, developing a fast-analytical mathematical model effectively efficiently find design rules for further application. results prove that air mass flow rate generated by in 0.9 m2 be as high 75.6 kg/h when radiation is 120 W/m2. comparison two models shows it feasible develop tool based on widely available MATLAB demand computing resources provide guidance how future should designed particular applications. study also investigated effects wider range channel height thickness (e.g., temperature, velocity, rate).
