Universal Combustion Device Stability (UCDS) Services

The Universal Combustion Device Stability (UCDS^™)

process provides detailed physical insight into the stability characteristics of complex combustion devices.  Using calculations that are based entirely on known or measurable parameters, it is now possible to predict for a given initial state the actual wave geometry, time history of the wave amplitude, limit amplitude reached by the wave system, and accompanying changes in the combustion chamber state properties. Design of corrective procedures can now be accomplished with full physical understanding of the action of damping mechanisms.  UCDS will allow developers to avoid expensive cut-and-try approaches and instead eliminate the risk of combustion instability with reliable engineering techniques

UCDS PRELIMINARY STABILITY ASSESSMENT

In the first recommended service, Gloyer-Taylor Laboratories LLC shall perform a preliminary assessment of the stability characteristics of your combustion device at five (5) operational conditions (e.g. nominal plus four off nominal cases).  Using the customer provided combustor geometry (simple or complex) and fluid properties, Gloyer-Taylor Laboratories shall apply the UCDS process to generate a suite of stability characteristic predictions.  This assessment will result in a technical report which shall include predictions of the:

    1) Oscillation Amplitudes

              Limit cycle amplitude vs. net surface admittance (i.e. burning or injection)

              Critical surface admittance vs. operational parameters (e.g. pressure, flow rates, and mixture ratios)

    2) Wave Characteristics

              Wave frequencies and full waveform geometry

              Time evolution of wave dynamics

              Time to reach limit cycle (or time to decay) vs. pulse size

    3) Mean Property Changes

             Changes in pressure, density, temperature and heating vs. time and at limit conditions

 

Using this preliminary stability assessment it will be possible to:

● Identify and quantify the risk of instability

● Understand the wave dynamics of an instability

● Predict the impact (structural and thermal risk) of an instability on the combustor hardware

● Develop a plan to eliminate or mitigate instability risk
