  text: Pillow-plate heat exchangers (PPHEs) represent a viable alternative to conventional
    shell-and-tube and plate heat exchangers. The waviness of their channels intensifies
    fluid mixing in the boundary layers and facilitates heat transfer. Applying secondary
    surface structuring can further enhance the overall thermo-hydraulic performance
    of PPHEs, thus increasing their competitiveness against conventional heat exchangers.
    In this work, streamlined secondary structures applied on the PPHE surface were
    studied numerically to explore their potential in enhancing near-wall fluid mixing.
    Computational fluid dynamics (CFD) simulations of single-phase turbulent flow
    in the inner PPHE channel were performed and pressure drop, heat transfer coefficients,
    and overall thermo-hydraulic efficiency were determined. The simulation results
    clearly demonstrate a favourable influence of secondary structuring on the heat
    transfer performance of PPHEs.</jats:p>

  text: Heat pumps play a crucial role in decarbonizing the chemical industry. The
    integration and sizing of heat pumps in chemical processes is a challenging task
    in multi-product chemical processes due to the fluctuating waste heat supply and
    heat demand. Integrating heat pumps may require a retrofit of the utility system.
    Mathematical optimization is a useful tool to tackle this challenge by enabling
    the analysis of correlation between relevant system parameters and equipment sizing.
    This study demonstrates the utilization of mathematical optimization and parameter
    studies for utility system equipment sizing addressing fluctuating heat supply
    and demand profiles.</jats:p>
