Hi Mark
Yep, an axial wheel can be horizontal and mounted on a vertical shaft .
Normally a turbo GT run with a vertical shaft would have oil leakage problems at the seals especially on shutdown , but in your case if you only use the hot section it won't matter as any oil leakage at the "comp end" would simply allow oil to enter the gearbox .
My high pressure fueling had a pump running at roughly constant speed feeding a control valve with a pressure differential valve to maintain a constant pressure drop across the metering oriface regardless of supply pressure to the fuel spray nozzle .
Cheers
John
