Applications of a novel wall-modeled large-eddy simulation approach combined with the immersed boundary method for studying turbulent flows through complex geometries

The study of turbulent flows and their interaction with geometrically complex objects remains a major challenge in engineering, particularly in the aerospace field. Accurate representation of the geometry, generation of computational meshes capable of resolving the flow field, and modeling of the near-wall region are key issues that must be addressed. A representative aerospace example is the flow over a wing with deployed high-lift devices, such as flaps or slats, where intricate interstitia...

Investigation of pump installation effects in outboard dynamic-inlet waterjet

Modern marine propulsion systems are primarily based on traditional screw propellers, but waterjet propulsion has gained attention as an innovative alternative due to its superior efficiency at high speeds and reduced cavitation effects. This thesis aims to investigate the hydrodynamic performance of a novel axial engine designed for zero-impact naval propulsion. The study, carried out as part of the university research project "Impronta Zero", utilises Computational Fluid Dynamics (CFD) simu...

Multi-point optimisation of outboard dynamic-inlet waterjet

The Outboard Dynamic Inlet Waterjet is an innovative propulsive system, chatacterized by an high efficiency, a low acustic impact and a remarkable propulsive efficiency, compared to traditional propulsive methods. This type of tecnology offers significant opportunities to improve the sustainability of mobility in particularly sensitive enviroments, such as the Venice lagoon. Through the Impronta-0 project we want to adapt this system to the specific case of the lagoon. This paper focuses on t...

Wingsails for a wind-assisted propulsion cruise vessel: aerodynamic analysis of the single sail performance and sail interaction study

This thesis consists of a study of a potential integration of a Wind Propulsion System in the design of a Cruise Vessel. The Wind Propulsion System consists of an array of rigid sails, which have a cross-section featuring an aerodynamic profile, the so-called Wingsails. Firstly, the context of the study will be provided, along with the problem set-up and a brief overview of the mathematical models used to simulate the system; then the single-sail aerodynamic performances will be assessed, wit...

Numerical simulation of hull installation of a novel outboard dynamic inlet waterjet

The present thesis investigates the propulsive performance and the installation effects of a novel waterjet concept for sustainable marine propulsion. This innovative system is called Outboard Dynamic-Inlet Waterjet (ODW) and it features a unique operational mode, being completely submerged and benefiting from an axial dynamic inlet and propulsive nozzle. Unlike traditional waterjets, the ODW’s biggest advantage is that it operates in an axial, uniform captured stream tube, resulting in highe...

Metamaterials Lens for electric space propulsion

La propulsione elettrica rappresenta un approccio moderno alla propulsione spaziale, basato sull'impiego di energia elettrica per accelerare un propellente, garantendo un elevato impulso specifico e una significativa flessibilità operativa. Tra le varie tipologie, i sistemi di propulsione senza elettrodi sfruttano onde elettromagnetiche per sostenere la scarica di plasma, eliminando l'erosione degli elettrodi e migliorando la longevità del sistema. Una delle principali sfide in questi disposi...

Numerical investigation of high speed propeller under boundary layer ingestion conditions

This thesis investigates the aerodynamic behavior of a transonic propeller operating in free flow and under Boundary Layer Ingestion (BLI) conditions. Through three-dimensional CFD , the interaction between the propeller and a non-uniform boundary layer were analyzed. The study aims to assess the influence of these operating conditions on aerodynamic performance and load distribution, offering a framework for future advancements in the design of high-efficiency propulsion systems.

Indagine numerica sull'instabilità del flusso nei paracadute durante il volo subsonico.

L'esplorazione di Marte è diventata sempre più importante nel corso degli anni e richiede missioni planetarie avanzate per studiarne l'ambiente. Per raggiungere questo obiettivo, è essenziale far atterrare sul Pianeta Rosso gli strumenti scientifici, consentendo ricerche e analisi. Durante la fase di ingresso, discesa e atterraggio (EDL), i paracadute svolgono un ruolo cruciale nel rallentare il veicolo spaziale. Tuttavia, il comportamento aerodinamico dei paracadute è complesso e può essere ...

Simulazioni ad alta fedeltà dell'effetto della rugosità su uno strato limite turbolento supersonico

Questa tesi si propone di fornire una modellizzazione efficace della rugosità superficiale e dei suoi effetti sui flussi comprimibili, con un'attenzione particolare allo studio della resistenza aerodinamica. In particolare, ho analizzato superfici con caratteristiche di rugosità definite per osservare come i loro parametri influenzino il flusso e le forze di resistenza. Mi sono concentrata su geometrie come cubi allineati, cubi sfalsati, cubi ruotati ed elementi a forma di diamante, calcoland...

Pattern di accoppiamenti albero-foro: metodo innovativo per la stima di Rejection Rate e Assembly Shift

Questo studio presenta un metodo numerico innovativo per la stima dell’Assembly Shift statistico in pattern di accoppiamenti albero-foro, considerando configurazioni con un numero variabile di elementi disposti nel piano e determinare la percentuale di scarto dovuta al fallimento durante l’assemblaggio. Attraverso l’implementazione di simulazioni Monte Carlo, in cui viene implementata anche una simulazione di assemblaggio virtuale, la metodologia proposta consente di stimare i Rejection Rate,...
