High-temperature heat pumps, particularly CO2-based systems, offer promising potential due to their favourable thermodynamic properties and environmental benefits. Drying processes typically operate at temperatures ranging from 60°C to 220°C, with hot air commonly used as the medium for heat transfer. Transcritical and supercritical CO2 heat pumps each have unique advantages depending on the temperature and pressure conditions of the process. This research investigates the performance characteristics of trans-critical and supercritical CO2 heat pumps in industrial drying applications, while identifying the break-even point between these two configurations, focusing on key parameters such as system efficiency and operational conditions. Thermodynamic modelling and performance simulations are employed to assess how variations in source temperature, system design, and operating conditions affect the choice between transcritical and Supercritical operation. Understanding this break-even point is crucial for optimizing CO2 heat pump systems for drying processes, ensuring that the system operates at peak efficiency while meeting the thermal demands of industrial drying. By examining these configurations in-depth, the study aims to contribute valuable insights into the potential for CO2 heat pumps to enhance energy efficiency, reduce environmental impact, and support more sustainable practices in the drying industry.

This paper cross-validates experimental and numerical results, focusing on the scaling of turbulence statistics at the pipe centerline and across the inner-outer flow region. Pipe flow experiments were reviewed for friction Reynolds numbers 810≤Re𝜏≤55×103, where Re𝜏=𝑢𝜏⁢𝑅/𝜈, 𝑢𝜏 is the wall friction velocity, 𝑅 the pipe radius, and 𝜈 the kinematic viscosity. Complementary DNS data for 180≤Re𝜏≤2880 provide detailed insight into near-wall turbulence. A novel friction correlation, Re𝜏=0.048Re0.923 c is introduced, predicting pipe-wall friction across a wide range of Re𝑐 with accuracy better than ±2.06%, where Re𝑐 is the Reynolds number based on the centerline streamwise mean velocity component 𝑈zc. This correlation enables reliable friction estimates from centerline single-point measurements or DNS data without requiring near-wall or streamwise pressure-gradient information and is validated by consistent agreement with both experiments and DNS. The monotonic decrease in centerline turbulence intensity ⟨𝑢′𝑧2⟩1/2/𝑈zc with increasing Re𝑐 is explained using the streamwise mean momentum equation. Finally, azimuthal spatial filtering of DNS data highlights the limitations of hot-wire resolution near the wall. For Re𝜏≥2880, higher-order experimental statistics agree well with DNS for 𝑦+≥30 and into the logarithmic region, with both datasets equally well described by logarithmic or power-law correlations, while near-wall discrepancies remain due to resolution limits.

To measure and maintain indoor air quality in terms of airborne transmission, an open source, low cost and distributed array of particulate matter sensors was developed and named Dynamic Aerosol Transport for Indoor Ventilation, or DATIV, system. This system can use multiple particulate matter sensors (PMSs) simultaneously and can be remotely controlled using a Raspberry Pi-based operating system. The data acquisition system can be easily operated using the GUI within any common browser installed on a remote device such as a PC or smartphone with a corresponding IP address. The software architecture and validation measurements are presented together with possible future developments.

The inertial wave excitation mechanism and its localisation at the edges was clarified by applying boundary layer theory. Additional resonance peaks in the simulated response spectra were found to agree with low-order wave attractors obtained by geometric ray tracing. Numerics and theory are in qualitative agreement with recent lab experiments.
