Evaluation of a jet plate solar air heater
WebThis article deals with the evaluation of selected aspects of abrasive water jet technology (AWJ) in the cutting of abrasion-resistant steel (HARDOX 500) with a thickness of 40 mm. The high abrasion resistance as a typical significant property of this steel ranks it among the special materials that are increasingly used. WebCooling by a transfer of heat by radiation from the plants to the cooler night sky was inhibited. This was possible only in the "open" experiments of 1931-1934 in Petersham (Pkaes 5 and 6). Under the Môller house in the 1930 experiments (Plates 3, 4 and 5) the glass roof would prevent radia- tional cooling of the plants outside the water-filter.
