报告内容简介:
Peristaltic pumping relevant to aerospace applications include cooling systems for aerospace electronics regarding efficient heat dissipation. Such phenomenon has key role for transferring liquids, specifically dealing with reactive materials where contamination is a major concern. Mechanical system applications of peristaltic pumping are in laboratory and research and industrial processes. Microfluidics and drug delivery and pharmaceutical and food processing industries may be mentioned in this direction. In robotics and automation, the peristaltic pumps can be integrated for tasks of liquid dispensing or dosing. Besides these an investigation of hydromagnetic peristaltic activity has significance in biomedical, engineering and industrial applications. Such consideration in medical processes has a pivotal role for treatment of diseases associated with liver, hernias, skin, jaundice, cancer therapy, gout and spam, nervous disorder and diagnosis by Magnetic Resonance Imaging (MRI). Importance of peristalsis cannot be denied when considering processes like biosensor, drug delivery, injury repair, vaccine adjuvant etc. Especially the peristalsis through electromagnetic fields is useful for pain control, wound healing, cancer gene therapy, bleeding reduction during surgeries, bone repair, electro-chemotherapy, nerve electrophysiology and particle filtrations. Motivated by these facts the hydromagnetic peristalsis of rheological material in an asymmetric channel will be addressed. Here constitutive equations in modeling will be employed for the generalized second order material. Formulation for two-dimensional flow will be made. Wave frame analysis in terms of stream function will be formulated. Long wavelength and small Reynolds number will be invoked. Solutions development will be numerically organized. Outcomes of pertinent variables for velocity, pressure gradient and streamlines will be studied with the help of graphs. Pumping and trapping phenomena will be discussed in detail. Comparative study for symmetric and asymmetric flow configurations will be organized. Graphical results will be analyzed physically. Important observations will be finally concluded.
