The influence of the plug shape on the performance of an aerospike nozzle thrust force is studied in different back pressure conditions. To generate smooth plug contours, Cubic B-Spline technique is employed. In the current research, basis functions are obtained using Deboor’s relation. The flow field around the aerospike nozzle is investigated implementing various shapes and the best of the ge...

A numerical framework for modelling platelet plug dynamics is presented in this work. It consists of an extension of a biochemical and plug growth model with a solid mechanics model for the plug coupled with a fluid-structure interaction model for the blood flow-plug system. The platelet plug is treated as a neo-Hookean elastic solid, of which the implementation is based on an updated Lagrangia...

In this paper we examine the effect of mild stenosis on blood flow, in an irregular axisymmetric artery with oscillating pressure gradient. The Herschel-Bulkley fluid model has been utilized for this study. The combined influence of an asymmetric shape and surface irregularities of constriction has been explored in this computational study. An extensive quantitative analysis has been performed ...

The meniscal allograft transplantation (MAT) has been reported to be an effective treatment in terms of pain relief and functional improvement in symptomatic meniscus-deficient knee. The medial MAT is usually performed with the bone plug technique or soft tissue fixation for root fixation. We describe medial MAT with modified bone plug technique that permits easy passage of posterior bone plugs...

In this paper, a very efficient method, called single matrix block analyzer (SMBA), has been developed to determine relative permeability and capillary pressure curves from spontaneous imbibition (SI) data. SMBA mimics realistically the SI tests by appropriate boundary conditions modeling. In the proposed method, a cuboid with an identical core plug height is considered. The equal dimensions of...

The purpose of this study is to determine the largest and smallest power values maximum change in BMEP on influence shape spark plug electrode tip a 150 cc motorcycle engine. This applies laboratory experiments as research method with open full-throttle test method. increased for each standard plugs yields highest 6.64 kW at 6000 rpm lowest 2000 2.04 kW. While spherical iridium produces 2.09 rp...

Safe and permanent closure of patent ductus arteriosus (PDA) can be accomplished with an ivalon plug introduced by catheterization from the femoral artery. The authors' experience thus far obtained from treating more than a hundred patients suggests that the technique described in this paper is a feasible alternative to the surgical approach. A prerequisite has been the size and shape of the PD...
