<p>A jet pump apparatus (15) for mixing a higher pressure gas (A) from a higher pressure gas supply (11) and a lower pressure gas (B) from a lower pressure gas supply (11b), the apparatus (15) including an inlet section (16), an outlet section (19), a diffuser section (18) and a mixing section (17), the inlet section (16) including a higher pressure gas inlet (22a) and a lower pressure gas inlet (24a), the mixing section (17) including a plurality of separated mixing chambers (25a-25d), and the diffuser section (18) including diffusers (26a-26d) for receiving mixed gases from each of the mixing chambers (25a-25d), and the outlet section (19) receiving mixed gases from the diffuser section (18) and conveying the mixed gases to a mixed gas outlet (35), and the inlet section (16) including a higher pressure gas inlet duct (22) which receives higher pressure gas from the higher pressure gas inlet (22a), and a lower pressure gas inlet duct (24) which receives lower pressure gas from the lower pressure gas inlet (24a), and for each of the plurality of mixing chambers (25a-25d), there being a primary nozzle (28a-28d) for introducing primarily higher pressure gas from the higher pressure gas inlet duct (22) to a respective mixing chamber (25a-25d), and there being a secondary inlet (34) for introducing primarily lower pressure gas from the lower pressure inlet duct (24) to each of the mixing chambers (25a-25d), the higher pressure gas being derived from a compressor section (11a) of a gas turbine engine (11).</p> |
