To examine the effectiveness of dual cooling circuits in lowering the wall temperature of the rp1 cooled engine, a dual circuit for this engine was designed. the dimensions of the cooling channels for both designs, single and dual circuits, are shown in figure 17. Commonly used cooling method in liquid propellant rocket engines. recent studies has shown that using coolant channels having high height to width ratios (aspect ratio) results in better cooling of the thrust chamber walls but implementing such channels along the entire len.

Regenerative Cooling - Zoefact

Regenerative Cooling - Zoefact This work introduces a custom numerical tool that predicts wall temperature and heat flux distributions using only the thermophysical properties of the combustion gases and coolant, without assuming heat transfer coefficients, temperature profiles, or using prior experimental data. The overall analysis includes a complete three dimensional analysis of the flow in the regenerative cooling passages, conjugate heat transfer in the combustor walls, and the effects of film cooling on the inside chamber. An analysis of the regenerative cooling jacket used on the rl10 3 3a engine manufactured by pratt and whitney for use in the centaur upper stage. this engine utilizes cryogenic lox/lh2 propellants in an expander cycle to produce 16,500 lbf of vacuum thrust. A one dimensional model for the cooling channel flow and heat transfer is used. the coolant properties are evaluated based on the nist database.

A one dimensional model for the cooling channel flow and heat transfer is used. the coolant properties are evaluated based on the nist database. When designing regenerative cooling systems, the heat transfer coefficients are very important to keep in mind. in our case, we have a hot side and cool side htc, and these values can be tweaked to adjust the temperature profile along the wall and boundary layers. The maximum wall temperatures predicted by the tdk rte model for rp1 lox cooling showed less than 7% difference from measured temperatures, validating its accuracy. In this study, the effects of geometry and number of cooling channels on the maximum temperatures of thrust chamber wall and coolant, and the pressure drop in cooling channel of a liquid propellant rocket engine are investigated.
