WebElimination of the effects of convection can be effected as follows: (a) by limiting the aper- ture through a tube arrangement, e.g., to 5°-10°; (b) by providing an envelope transparent to the atmospheric radiation and at effectively the same temperature as the receiver; (c) by providing an artificial heat loss so great as to swamp the effect of natural convection; (d) … WebIt is replaced by the cooler, denser water which surrounds it. This water is in turn heated, expands becomes less dense and rises. The process continues, a convection current is …
