Realise the sustainable promise of hydrogen combustion with simulation

Hydrogen is poised to decarbonise many sectors of our economy. It can be directly used in fuel cells for carbon-free power, or in gas turbines, where its high-energy density, higher autoignition temperatures and ability to lean-burn are favoured.

The Paris Climate Agreement and the aviation community’s commitment to lower emissions drastically by 2050 are also driving hydrogen combustion research and development.

Despite its potential as a “golden” fuel or energy carrier, burning hydrogen in engines poses several challenges, including flashback, acoustic instabilities, autoignition, and flame
holding inside the burner. Engineers can address these challenges with simulation.

Simulation saves time and costs

Rig testing does provide valuable information to
help combat these challenges, but is expensive and time consuming, and with 100 percent hydrogen, it can mean sacrificing the critical components and instrumentation
of the rig. Numerical simulations can provide a deeper characterisation of many complex phenomena inside gas turbine combustion chambers...
