Rowing is a competitive sport where victory is determined by fine margins. In the past, the focus has been on optimizing the shell. Due to the increasing regulations placed on the shell design, the scope for manoeuvring in this area is greatly limited. This increases the necessity to focus on the less explored option of propulsion in rowing. The...

Emulsions and foams are commonly found in products made by industries ranging from those
associated with food and pharmaceuticals to those involved in selling personal care products.
This work is motivated by the need for accurate models of their mechanics, which can then be
used for efficient processing.

They can be thought...

Steady state multiphase flow models are used for the design and operation of pipelines that are used in the oil and gas industry. The predictions obtained with these models contain uncertainties, which arise from model assumptions and simplifications, and from uncertainties in the input parameters. In this thesis we investigate the effect of...

This study was aimed at improving the accuracy of the model predictions for the minimum fluid and inner wall temperatures for cold, low-pressure start-up of wells that produce oil or gas. Due to the large pressure drop over the well head choke, the so-called Joule-Thomson cooling will give a very low temperature of the
expanding gas jet. Low...

Broadband turbulent noise can lead to fluid-acoustic and fluid-structure interaction and ultimately to mechanical failure of pipe systems. In HVAC (Heating Ventilating and Air Conditioning) systems broadband turbulent noise can radiate outwards where it is a nuisance or even harmful to people. A fast and simple approach for investigating...

The aim of this thesis is to study the effect of pre-rotation on the performance of an axial flow pump manufactured by Xylem Flyght. Through theory and experiments, it is known that pre-rotation or swirl in the flow is an adverse effect, as it reduces the efficiency of the pump system. But the extent of this effect cannot be predicted to good...

Natural gas wells produce small amount of liquids along with the gas. During the initial part of the reservoir life, the gas velocity in the well tubing is large enough to drag the liquid upwards. As the well matures, the reservoir pressure starts to decline leading to a decline in the gas velocity in the tubing; here the gas momentum is not...

An attempt is made to evaluate all possible stress based failure criteria that have been otherwise traditionally used for ductile metals and also some other criteria popularly used for polymers. In additional some other intuitive criteria were also derived.

We developed bio-inspired reduced-order models of swimmers, consisting of a self-propelling pair of rotating cylinders. The aim of the project is twofold. First, simplified and non-deforming geometries can more easily be employed in small-scale robotic applications to solve relevant engineering problems. Second, they can serve as reduced physics...

This work explores predictability in atmospheric flows. A study on forecasting is conducted in the Lorenz [1963] model using several Data Assimilation techniques. Methods of statistically combining model forecasts with observations for prediction are tested for their performance, which readily extend to higher dimensional systems and are oft...

Direct numerical simulations of transient turbulent channel flow were conducted in order to study and characterize the large-small scale interaction in this type of flows. This was achieved by analyzing some well-known universal aspects of turbulence. Additionally, the so called strain-rate-eigenframe analysis was applied to study the local flow...

Step cylinders have numerous applications, for instance, radio communication towers, airport control-towers, antenna members, etc. Numerous applications motivate researchers to investigate this bluff body both numerically and experimentally. The single step cylinder model is comprised of a small-diameter cylinder (d) attached coaxially to a...

For channel flow, we explore how a hairpin eddy may reach a threshold strength required to produce additional hairpins by means of auto-generation. This is done by studying the evolution of two eddies with different initial strengths (but both below the threshold strength), initial sizes and initial stream-wise spacing between them. The...

The most recent studies of intermittent state in linearly stable shear flows, like pipe, Plane Couette and Taylor Couette flow, have shown that turbulent structures, created by finite-amplitude perturbation, have an exponential distribution of the lifetimes. Here we experimentally examine the lifetime of turbulent spot in Taylor Couette flow ...
