Thermal control for the two-beam module of the compact linear collider with computational fluid dynamics simulations of conjugate heat transfer problems, with subsidiary finite-element simulations

Conjugate heat transfer simulations were performed for the two-beam module of the Compact Linear Collider (CLIC). A full approach using ANSYS Fluent is presented for the determination of heat dissipation values from the main beam portion of the module to the cooling air and water. A transient model for heat dissipated through the tunnel to the outside soil is presented as well. Structural stress-strain simulations and modal analyses were performed for the adjustable supports with the finite-element method using ANSYS Mechanical. The operating range of the adjustable supports was determined.
