High efficiency, environmental friendliness, low operation and maintenance  costs, and the lowest possible impact on the environment are some of the requirements of sustainable energy production. In the selection of new ...

In this investigation, the instantaneous unsteady heat transfer within a pneumatically driven rapid compression-expansion machine that offers simple, well-controlled and known boundary conditions was studied. Values of the ...

The purpose of this paper is to develop analytical-numerical solutions to work out the longitudinal temperature changes of flow in the passages of a plate heat exchanger. The solution for a general variation in U, except ...

Streamline curvature is still a powerful method in predicting the performance of turbomachines whose results will be more realistic if a good estimation of losses and deviation is incorporated in the calculations. The ...

An analysis of rib-stiffened columns is made in the present study, employing the energy method with three sinusoidal terms in the assumed deflection function. A total of 325 design curves are determined and plotted showing ...

Pipes with non-circular cross sections made by reshaping processes are widely used as struc­tural elements in almost all industries. Despite a long history of the process, because of the complicated deformation behavior ...

Local bifurcation of the attitudinal dynamics of the torque free rigid body motion is discussed. Hamiltonian formalism is used to express equations of motion. To simplify attitudinal dynamics of a rigid body, six dimensional ...

An analytical investigation of the buckling problem of composite shells with radius variation is presented. Different types of loading such as compressive and external can be applied. Flügge's shell equations, modified for ...

GMDH-type neural networks are used for the modelling of explosive welding process of plates. The aim of such modelling is to show how the geometric characteristics of the bonding interface such as amplitude and wave length ...

Propagation of shock waves over a cylinder, sphere and projectile are numerically simulated. Time dependent full Reynolds averaged Navier-Stokes equations are solved numerically with Roe's scheme. For cylinder and sphere, ...

This paper investigates the effect of structural damping on the chaotic behavior of  nonlinear panels in supersonic flow. The nonlinear governing equations, based on Von Karman's large deflection of isotropic flat plates, ...

Feedback linearization is a systematic approach often applied to the dynamic model of mobile robots and ground vehicles. It transforms a nonlinear system into a (fully or partially) linear system, and then uses the well-known ...

In this paper we present our modeling approach for studying the role of the shoulder muscles in the bowling (swinging) of a ten pin bowling ball and the moments,  stresses and forces that are induced on the shoulder. Three ...
