The effect of a point heat source on the two-dimensional irrotational flow of a slightly compressible nonviscous and nondiffusive fluid is studied. Heat is added at a constant rate and with a prescribed spatial distribution. The Mach number M is assumed small and the governing equations are solved to order M 2 by a generalization of the Rayleigh-Janzen expansion. The interaction between entropy...

The three-phase-lag model and Green–Naghdi theory without energy dissipation are employed to study the deformation of a two-temperature fiber-reinforced medium with an internal heat source that is moving with a constant speed under a hydrostatic initial stress and the gravity field.  The modulus of the elasticity is given as a linear function of the reference temperature. The exact expressions ...

in order to study the effects of post – anthesis heat stress on source of six wheat genotypes (vee/nac, chamran, s79-10, dez, fong and kaveer), two separate field experiments were conducted as delayed as against optimum sowing dates in ahvaz coditions. plants in delayed sowing date experienced heat stress at post-anthesis growth stage. as study of grain yield indicated that the highest and the ...

This paper investigates the time evolution of the near-isobaric flow field produced in a gas after the sudden application of a constant heat flux from a localized energy source. The problems of plane, line, and point heat sources are all investigated, with a power law for the temperature dependence of the thermal conductivity, after reduction to a quasi-linear heat equation for the temperature....

Recently, the efficiency of computer modeling and simulations has been improving dramatically. Consequently, the structural analysis of welding phenomena based on thermaleelasticeplastic finite element method (FEM) can be performedwith a good accuracy in a short time. However, if themodel to be analyzed is large and it has a complex shape, problemsmight occur with preprocessing, such as themesh...

The influence of non-uniform slot suction (injection) into a steady, MHD boundary layer flow over a sphere with variable viscosity has been examined. The system of nonlinear, coupled partial differential equations governing the non-similar flow have been solved numerically and the solutions have been obtained from the starting point of the streamwise co-ordinate to the exact point of separation...
