Flow Optimisation through Porous Ceramic Throttle
نویسندگان
چکیده
Dynamics of fluids in porous media is of importance in many fields of practical interest. Currently scientists at the Medical Sensors and Devices Laboratory at the Luebeck University of Applied Sciences are developing a throttle system for a gas-driven infusion device whose centrepiece consists of a nanoporous ceramic unit for regulating the flow in the range of microto nanoliters per minute. Aim of the present paper is to obtain a better understanding regarding the underlying flow phenomena through already existing specimen to improve their actual design. Against this background several measurements were done, including Micro-CT scanning of the present samples and determination of the fluid flow in the course of experimental set-ups. Combined with flow simulations using actual dimensions of the investigated specimen a validation of the existing throttle concept is possible.

Pain alleviation is one of the most important therapies for chronic or incurable diseases. Consequently, implantable infusion pumps are challenged to provide long-term medication with extended check intervals. With the aim of a treatment serving each patient’s individual symptoms pattern, current research focuses especially on the possibilities of adjustable drug flow implementation. Programmab...
متن کاملModeling And Simulation of Gas Flow Velocity In Catalytic Converter With Porous
Stringent emission regulations around the world necessitate the use of high-efficiency catalytic converters in vehicle exhaust systems. Experimental studies are more expensive than computational studies. Also using computational techniques allows one to obtain all the required data for the Catalytic Converter, some of which could not be measured. In the present work, Geometric modeling ceramic ...
متن کاملDevelopment of Porous Piezoceramics for Medical and Sensor Applications
The use of porosity to modify the functional properties of piezoelectric ceramics is well known in the scientific literature as well as by the industry, and porous ceramic can be seen as a 2-phase composite. In the present work, examples are given of applications where controlled porosity is exploited in order to optimise the dielectric, piezoelectric and acoustic properties of the piezoceramic...

Throttle body assembly plays a vital role in metering the airflow. It mainly consists of a butterfly valve to vary the flow area to control air flow rate through it. There is hardy any established procedure to design a throttle body assembly based on the engine specifications. In order to bridge the gap, this study, design and optimization of a throttle body assembly for a single-cylinder engin...
متن کاملUnsteady free convection oscillatory couette flow through a variable porous medium with concentration profile
In this paper we have studied the effect of free convection on the heat transfer and flow through variable porous medium which is bounded by two vertical parallel porous plates. In this study it is assume that free stream velocity oscillates with time about a constant mean. Periodic temperature is considered in the moving plate. Effect of different parameters on mean flow velocity, Transient ve...
