Abstract:

This report aims to investigate how fluid-based heat-recovery systems for ventilation can be optimized. A high proportion of existing systems operate at lower efficiency than possible, and thus do not reach their full potential in terms of energy savings. The aim of this report has been to find out why, to identify which parameters affect the efficiency of such systems, and to develop a general methodology for optimization. As a method for execution, a literature study and field experiments were chosen. The results from the literature study showed that dimensioned efficiency, fluid flow in the

Abstract:

This study is concerned with the recovery of fluid mechanical modes that can be used to describe the physical properties of unsteady separated flows. The flow configuration of interest is a spanwise homogeneous NACA 0015 airfoil with leading edge laminar separation and turbulent recirculation. An in-depth understanding of the unsteady flow dynamics and fluid mechanical stability properties, can assist in the future development of more efficient separation control strategies. In order to provide a richer understanding of the physics, the flow fields are numerically generated, and characterised

Abstract:

A typical long-haul heavy duty Diesel engine currently rejects up to 50% of the total fuel energy in the form of heat. Due to increasing CO2 emissions and fuel costs, there is a growing interest in techniques that can even partially utilise this wasted resource to improve the overall system efficiency. Fluid Bottoming Cycles (FBC) including Rankine and organic Rankine cycles offer one means towards converting waste heat into usable power. This thesis investigates the potential of FBCs to improve the net power of two computationally modelled (Ricardo WAVE V8.1) 10 litre engine platforms operati

Abstract:

The study of multiphase flow in porous media is highly relevant to many problems of great scientific importance, such as CO2 storage and enhanced oil recovery. Even though significant progress has been made in these areas, many challenges still remain. For instance, the leakage of stored CO2 may occur due to the capillary trapping failure of cap rock. Approximately 70% of oil cannot be easily recovered from underground, because the oil is held in tight porous rocks. Although CO2 storage and enhanced oil recovery are engineering processes at a geological scale, they are predominantly controlled

Background: Athletes undertaking frequent training or those involved in sporting competitions with multiple heats or games may be required to complete two or more high-quality exercise sessions with limited recovery time between bouts (e.g. ≤4 h).

To achieve this, any system has to collect sufficient sample volumes to ensure statistically valid characterisation of the sampled fluids.

Abstract:

This thesis is concerned with the modelling of miscible fluid flow through porous media, with the intended application being the displacement of oil from a reservoir by a solvent with which the oil is miscible. The primary difficulty that we encounter with such modelling is the existence of a fingering instability that arises from the viscosity and the density differences between the oil and solvent. We take as our basic model the Peaceman model, which we derive from first principles as the combination of Darcy’s law with the mass transport of solvent by advection and hydrodynamic dispersion.

Abstract:

The diffusion absorption refrigeration (DAR) cycle is a promising technology for fully thermally driven cooling. It is well suited to applications in medicine refrigeration and air-conditioning in off-grid settings. However, design and engineering knowhow for the technology is limited; therefore, system development has historically been an iterative and expensive process. Additionally, conventional system designs require high-grade energy input for operation, and are unsuitable for low-temperature solar- or waste-heat activated applications. In the present effort, component- and system-level

Abstract:

This thesis examines the viability of waste heat recovery from a small scale, low temperature hydrogen fuel cell, to generate additional power using a thermodynamic cycle and micro-turbine. It investigates the optimal fluid selection for an organic Rankine cycle and models a radial inflow turbine to generate power from the cycle, which was able to improve the efficiency of the fuel cell by 5%. This work optimises the cycle and turbine designs to match the operating conditions and achieve the highest efficiency and validates the result using 3D fluid simulations.

<p>The thesis is based in a constructed light vehicle that must be improved by adding a hydraulic energy recovery system. This vehicle named as TrecoLiTH, participated in the Formula Electric and Hybrid competition (Formula EHI) 2009 in Italy -Rome- and won several awards.</p><p>This system consists in two hydraulic motors hub mounted which are used to store fluid at high pressure in an accumulator when braking. Through a valve the pressure will flow from the high pressure accumulator to the low pressure one, and consequently the vehicle will get extra acceleration.</p><p>This thesis consists

Abstract:

The decline of oil reserves has been observed in recent years and generates interest in developing new technologies that can make the most of existing wells and reservoirs in order to increase oil recovery. For this purpose, methods and enhanced secondary recovery of oil are used, which consist of injecting fluids targeting a certain pressure increase in the tank or changes in physical properties of oil to a larger and more efficient production. The method of secondary recovery that stands out, and the most common is the water injection. This method has proved effective for recovery of heavy o

Abstract:

O avanço da capacidade do processamento dos computadores e do desenvolvimento de métodos numéricos tem proporcionado ferramentas de modelagem, projeto e otimização cada vez mais eficientes para a constante melhoria de caldeiras de recuperação química Kraft. Dentre as técnicas utilizadas, os modelos CFD abrangentes tem sido empregados nos últimos anos para representar a operação da caldeira de recuperação considerando o maior número possível processos vinculados ao escoamento dos gases de combustão. O presente trabalho busca desenvolver um modelo CFD abrangente considerando o escoamento turbule

Abstract:

Various academic studies show that in the use of common ICE Off-road Vehicles only about 10-15% of the available power at fuel level is actually transformed into useful energy for the actuators. Particularly the Directional Control Valves are responsible for the dissipation of about 35-40% of the hydraulic energy available at the pump level. The machine electrification trend makes it even more urgent to optimize the hydraulic system to ensure greater performance and higher battery autonomy. Traditional Directional Control Valves design solutions neglect important opportunities for reducing los
