On shock structures in dynamic exhaust valve flows

Dynamic Clustering for Auto-organized Structures in Complex Fluid Flows

This paper presents an original approach for the detection of auto-organizated coherent structures in a fluid flow simulation. This method is based on vortex methods and multiagent systems. We then use automata to simulate the interactions between these structures and the induced evolution of their stability.

Effect of Contact Pressure and Frequency on Contact Heat Transfer Between Exhaust Valve and its Seat

The hot gases produced by the internal combustion engines passes through the exhaust valve and causes high temperatures in the exhaust valve and its seat. To avoid damaging the exhaust valve, heat must be transferred from the valve to its seat during the contact they make at the opening and closing cycle. Heat transfer rate from the exhaust valve to its seat is a function of many factors. One o...

Selfish Routing on Dynamic Flows

Selfish routing on dynamic flows over time is used to model scenarios that vary with time in which individual agents act in their best interest. In this paper we provide a survey of a particular dynamic model, the deterministic queuing model, and discuss how the model can be adjusted and applied to different real-life scenarios. We then examine how these adjustments affect the computability, op...

Relationship Between Financial Crisis And Oil Shock And Its Effect On East- West Asia Trade Flows

Relativistic Flows after Shock Emergence

We investigate relativistic flows after a shock wave generated in a star arrives at the surface. First, the sphericity effect is involved through a successive approximation procedure by adding correction terms to an already known self-similar solution in the ultra-relativistic limit assuming the plane parallel geometry. It is found that the lowest order correction terms are of the order of (a/R...
