Abstract:

Basic heat transfer and flow friction design data are presented for three straight, triangular passage, glass-ceramic heat exchanger surfaces. These surfaces have heat transfer area density ratios ranging from 1300 to 2400 foot squarefoot cubed, corresponding to a passage count of 526 to 2215 passages per sq. in. Glass-ceramic heat exchangers are of importance to vehicular gas turbine technology as they give promise of allowing low mass production costs for the high effectiveness rotary regenerator required in most of the vehicular turbine engine concepts now under development.
