... the tube to contract and extend the wire, respectively. The thermomechanical model presented in this paper accounts for the nonuniform temperature change of the SMA wire due to alternating the temperature of the flow along the wire. The thermal portion of the model consists of analysis of the heat transfer...

... ( y , z ; t ) − T a ( t ) ] + ε ( y , z ) b [ T 4 ( y , z ; t ) − T a 4 ( t ) ] with T a the ambient temperature of the PA gas (K), h a is the convective heat transfer coefficient ( W ∕ m 2 K ) , ε...

... model is developed for diesel active lean NO x catalysts. The model represents the phenomena relevant to NO x reduction and HC consumption, namely, the catalyst chemical reactions, HC storage in the ALNC, and heat transfer behavior on the basis of an individual exhaust element. As an illustration of how...

... convection identification Galerkin method differential equations Karhunen-Loeve transforms reduced order systems heat transfer Kalman filters When a fluid system is heated or cooled by the heat flux imposed at the boundary, thermal convection usually occurs. In many industrial applications...

... experimentally with the same speed control valves, when load mass or initial pressure at the discharge chamber was changed. The different equilibrium velocities are explained by the air temperature change. Experiments are simulated using a cylinder model considering heat transfer. Experimental and simulation...

.... The Wieting correlation has been used to compute the local convection heat transfer coefficient and friction factor. The model has been verified against steady-state experimental data and then incorporated into an engine cycle simulation program based on “Filling-Emptying” method. Two engine transients have...

...Kenji Kawashima, Research Associate,; Toshiharu Kagawa, Professor; Toshinori Fujita, Research Associate In this paper, a chamber called an “Isothermal Chamber” was developed. The isothermal chamber can almost realize isothermal condition due to larger heat transfer area and heat transfer...
