Steam cracking of hydrocarbons is and will continue to be the main industrial process to produce light olefins in the coming decades. In state of the art steam cracking plants more than 90% of the CO2 emissions can be directly related to the high ene

Spherical dimples are implemented in heat exchanger channels to enhance heat transfer at a low pressure drop penalty. This combination of enhanced heat transfer and low pressure drop is also valuable for reactive applications such as steam cracking a

Recently computational fluid dynamics (CFD) has been successfully applied for the evaluation of the start-of-run performance of three-dimensional (3D) coil geometries in steam cracking reactors. However, determining the full economic potential of a c

Obstacles placed on the inner walls of pipes lead to flow separation and subsequent reattachment with an overall beneficial effect on the local heat transfer. In this work, the effects of both a continuous and a discontinuous helicoidal turbulator on

A constant search for more efficient heat exchangers motivates the use of innovative turbulators. Original flow-field measurements were performed with S-PIV to gain a better understanding of the role of 3-D wall obstacles in pipe flows. Such effects

Spherical dimples in cylindrical tubes enhance heat transfer and lead to a more uniform radial temperature profile. To combine these positive properties with a low pressure drop, a single dimple was optimized through a genetic algorithm. Multiple des
