TDK’04^TM

The Analysis Tool For Liquid Rocket Engines

TDK is the JANNAF Standard computer program for the prediction of nozzle performance of liquid propellant rocket engines (LRE‘s). TDK’04™ analyzes and summarizes the performance loss mechanisms into four categories: Combustion chamber losses, Boundary Layer losses, chemical kinetics losses, and divergence losses.
 

The TDK’04™ is fast and robust enough to provide performance predictions for extensive parametric studies and sufficiently accurate to provide flowfield and performance solutions for detailed studies.

TDK’04™ contains the following features and capabilities:

• Uses a Two-Dimensional Method of Characteristics solution with fully coupled finite rate kinetics.

• Models chemical reactions with a generalized reaction package that includes 3rd body efficiencies and four different reaction rate forms.

• TDK’04™ optionally performs flow solutions with frozen or equilibrium chemistry.

• Provides planar or axially symmetric flow solutions.

• Supports both upper and lower wall flow simulations.

• Treats planar flow/external flow interactions.

• Incorporates the mass addition boundary layer, MABL, module, which includes finite rate chemical kinetics. This module optionally performs frozen or equilibrium chemistry.

• The MABL module treats mass injection at the wall for tangential slot injection or transpiration cooling.

• Improved accuracy and precision from prior versions due to better algorithms and coding changes.

• Incorporates a direct search Nozzle Contour Optimization (NCO) module which finds the best performing skewed parabola nozzle contour including kinetics and boundary layer effects.

• Treats discrete shocks: attached or induced.

• Models equilibrium radiation heat transfer for the wall (incorporated in the MABL Boundary Layer Module).

• Models variable mixture ratio profiles from the combustion chamber injector.

• Models combustion effects due to injector inefficiencies.

• Models droplet vaporization using the Spray Combustion Analysis Program (SCAP) Module.

• Provides engine performance predictions for axially symmetric nozzles, scarfed nozzles, plug nozzles, and scramjet nozzle configurations. The plug nozzle module includes a base pressure correlation.

• Provides an extensive post-plotting package for flow field visualization, including support for postscript, laser jet printers and Tecplot^TM

• Provides an interface for the JANNAF standard plume code SPF3 Version 3.2.

• Improved user interface for PC users.

The TDK’04™ code is available on the following platforms:

• IBM RS 6000
• Silicon Graphics
• SUN SPARC
• Pentium or equivalent PC platforms using the Windows 95/98/NT/2000/XP operating systems, or RedHat Linux.
