Response Surface Based Design Optimization of a Low-Pressure Microresistojet's Heat Exchanger

A Low-Pressure Micro-resistojet (LPM) is a type of in-space electrothermal propulsion system for satellites that works by heating low-pressure (50 to 300 Pa) fluid flowing through microchannels/slots (typically <1 mm diameter) using resistive heating elements like thin-film Molybdenum. This thesis delineates a response surface based method to...

High-dimensional numerical optimization of fiber reinforced polymers with variational autoencoders and Bayesian optimization

Designing engineering structures relies on accurate numerical simulations to predict the behaviour of a structure before its realization. In the design process, many variables influence the final structure. There is an incentive for optimizing the design based on the desire for cheaper structures and less material usage. Although a wide variety...

Thermal Management of a Data Center White Space: A numerical study using computational fluid dynamics, flow & temperature predictions using neural networks, and white space design optimization using a genetic algorithm.

The total electrical energy consumption by all the operational data centers (located all over the world) is enormous (approx. 1% of the global electricity demand 20000TWh). This electrical energy is required 24x7 to operate and cool all the IT equipment present in the data center. The electrical energy required to cool all...

Predicting scour around offshore wind turbines using soft computing techniques

In this report a prediction method is developed for scour around monopiles. A soft computing technique called genetic programming (GP) is used to create a scour prediction formula that can compute scour in all offshore conditions, meaning current-induced, wave-induced and combined current- and wave-induced scour. The GP was trained with an...
