THERMO-GEOMETRIC PARAMETER EFFECTS ON CONVECTIVELY COOLED INHOMOGENEOUS RECTANGULAR FIN

Maximal thermo-geometric parameter

A nonlinear heat conduction equation is studied, and the maximal thermo-geometric parameter in the equation is analytically determined, above which thermal instability occurs. The first-order result yields an acceptable error, and the variational iteration method is recommended for a higher accurate prediction. 2010 Mathematics Subject Classification: 35K05, 35Q79, 80A20, 34B15

Geometric Programming with Stochastic Parameter

Geometric programming is efficient tool for solving a variety of nonlinear optimizationproblems. Geometric programming is generalized for solving engineering design. However,Now Geometric programming is powerful tool for optimization problems where decisionvariables have exponential form.The geometric programming method has been applied with known parameters. However,the observed values of the ...

Multi-boiling Heat Transfer Analysis of a Convective Straight Fin with Temperature-Dependent Thermal Properties and Internal Heat Generation

In this study, by using the finite volume method, the heat transfer in a convective straight fin with temperature-dependent thermal properties and an internal heat generation under multi-boiling heat transfer modes are analyzed. In this regard, the local heat transfer coefficient is considered to vary within a power-law function of temperature. In the present study, the coexistence of all the b...

Thermo-viscous effects on finite amplitude sound propagation in a rectangular waveguide

The role that thermo-viscous effects play in the propagation of finite level sound in a waveguide has been reexamined from a fundamental perspective. In the past, nonlinear acoustic interactions have been described by energy conserving modulation of spectral amplitudes as wave packets travel axially down the waveguide. To account for thermo-viscous effects in this modulation, investigators have...
