Dry Powder Inhalers (DPIs) have great potential in pulmonary drug delivery; the granular powder, used as active ingredient in DPIs, is ozone friendly and the operation of DPIs ensures coordination between dose release and patient inhalation. However, the powder fluidisation mechanisms are poorly understood which leads to low efficiency of DPIs with 10-35 % of the dose reaching the site of action. The main aim of this thesis is to study the hydrodynamics of powder fluidisation in DPIs, using experimental and computational approaches.

Abstract:
Spray drying is an economical drying method for converting aqueous solutions into stable dry powders. This one-step continuous process generates a sustainable solution for long-term storage of various protein formulations. This study focuses on recombinant growth factors produced in a barley seed host. The retained bioactivity of the growth factor in the final solid form suggests that co-purified host components may have preserving effects throughout the optimized spray drying process. To identify the critical spray drying parameters, a customized response surface design of experiment was appl

Abstract:
Abstract Black powder, a mix of iron sulfides, oxides, and other material can represent a serious threat to the integrity of pipelines by plugging pipelines, eroding compressor components, plugging instrumentation and pipeline drips, preventing valid in-line inspection by In-Line Inspection (ILI) pigs, and causing damage to customer equipment. However, black powder may not be a problem until it starts to move due to fluid velocity. The velocity to cause movement of dry black powder in pipelines is presented for black powder in gas pipelines. Once black powder starts to move, it will continue t

Abstract:
Abstract The residue from the combustion of high-ash coal affects the design and operation of steam electric-generating plants. Proper boiler design can minimize the amount of retained ash, but accumulations over long periods of operation will affect boiler efficiency. Ash deposits on the tube banks will alter air flow and thereby heat transfer. Operating efficiency decreases and the cost of power generation increases. The method for dry removal of coal-ash described herein is aimed at regaining the design operating efficiency of the boiler with minimum disruption of power-generating operation

Dry cooling towers are an alternative cooling method when large quantities of water are not available. Examples of the proposed applications are the enhanced geothermal and concentrated solar thermal (CST) power plants in arid or semi-arid areas, like south-western United States, Australia, western Asia, north-western China and the rest of the world. Natural draft dry cooling towers (NDDCTs) have received widespread attention because they do not consume water, have low maintenance requirements and cause small parasitic losses. Unfortunately, the performance of a NDDCT is severely reduced when

Abstract:
Abstract Dry powder inhalers (DPIs), used as a means for pulmonary drug delivery, typically contain a combination of active pharmaceutical ingredient (API) and significantly larger carrier particles. The micro-sized drug particles — which have a strong propensity to aggregate and poor aerosolization performance — mixed with significantly large carrier particles that are unable to penetrate the mouth-throat region to deagglomerate and entrain the smaller API particles in the inhaled airflow. The performance of a DPI, therefore, depends on entrainment the carrier-API combination particles and th

Abstract Uncertainty around the design and control of the supercritical CO2 power cycle must be reduced before this technology can be implemented for large-scale grid support.

There are also requirements that the fuel system quickly stop the flow of fuel and vent appropriate lines in the case of a load rejection or an emergency shutdown.

We filtered ~107 m³ of clean Antarctic air through 20 cm diameter, 3 µm filters coupled to a suction blower of modest power consumption (5–6 kW).
