Wettability on nanoparticle modified surface: for thermal engineering
In many thermal engineering applications, manipulation of the wetting behavior of liquids is used as a heat transfer enhancement strategy. Hydrophilicity, implying better wettability of liquid on solid surface, is preferred in some processes of air-conditioning and power-generation systems, such as …

Application of probabilistic deep learning models to simulate thermal power plant processes
Deep learning has gained traction in thermal engineering due to its applications to process simulations, the deeper insights it can provide and its abilities to circumvent the shortcomings of classic thermodynamic simulation approaches by capturing complex inter-dependencies. This works sets out to …

Application of Bayesian-based uncertainty and global sensitivity analyses to spacecraft thermal design
… has increased in complexity, the evolution of thermal engineering of spacecraft has plateaued. For years, thermal engineers have used the same principles of designing to stacked worst case scenarios and applying additional margin on top of the already conservative predictions. Recent …

Dynamic modeling of a steam Rankine Cycle for Concentrated Solar Power applications
… but can also be applied in other fields of thermal engineering. They proved to be more robust and much faster than the traditional models, which was the objective. However, in the scope of this work, it has not been possible to validate them with experimental data or with more detailed …

Two-dimensional Wakes and Fluid-structure Interaction of Circular Cylinders in Cross-flow
… dynamics that plays a central role in civil engineering, ocean engineering and thermal engineering. In this work, a flowing soap film was used to investigate the wakes of multiple stationary circular cylinders and of a single oscillating cylinder. Corresponding computer simulations were also …

An investigation of drone propeller noise generation in a turbulent wake
Unmanned Aerial Vehicles (UAVs) are becoming popular as they can be used in a range of applications including surveillance, delivery, agriculture, aerial photography and search and rescue. As propeller noise can dominate the acoustic signature of a UAV, it is important to understand the noise …

Refurbished and 3D Modeled Thermal Vacuum Chamber
… testing includes acoustics, vibrations, and thermal vacuum. Cal Poly’s Space Environments Lab is equipped with multiple vacuum chambers, but no thermal vacuum chamber. The purpose of this thesis is to incorporate an ATS Chiller system with the HVEC vacuum chamber so students are able to …

Humidification Processes in Gas Turbine Cycles
… evaporative cycle has resulted in an increase in thermal efficiency from 21% to 35%. A theoretical model has been developed for the humidification process that predicts the height of the humidification column with an error of 10?15%. Thermodynamic analysis of the bio-EvGT has been performed which …

Frequency-domain modelling of floating wind turbines
The development of new types of offshore wind turbine on floating platforms requires the development of new approaches to modelling the combined platform-turbine system. In this thesis a linearised frequency-domain approach is developed which gives fast but approximate results: linearised models of …

On Model Libraries for Thermo-hydraulic Applications
… simulation are important tools when dealing with engineering systems that today are becoming increasingly more complex. Tightly integrated production and process optimization are trends that give rise to heterogeneous systems, which are difficult to handle without expertise in several engineering …
