Results of numerical simulations of the laser-induced boiling at the end of waveguide placed inside the tube are presented. The effect of tube wall on the vapor bubble evolution and characteristics of the cumulative jet forming as a result of its collapse has been studied. Particularly, it is found that while the tubes of large radii insignificantly affect the velocity of the cumulative liquid jet, in the relatively narrow tubes the jet may not form at all. Effect of the tubes of moderate radii comes down to the decrease of the jet velocity compared with the case without the tube. Possible physical explanation of such influence of tube walls is proposed. Numerical results on laser-induced boiling inside the tubes are summarized in the regime diagram in the tube radius - waveguide radius plane.

The paper deals with nonlinear convective heat transfer in a horizontal air layer overlaying a heat-generating porous medium saturated with air. The composite air/porous system is bounded by the top and bottom solid permeable planes of equal temperature and forced by a vertical throughflow. The upward throughflow enhances heat flux through the air-porous interface, while the downward one reduces it with increasing the flow velocity or relative air layer depth. In the presence of a uniform energy source and basic throughflow, there are favorable conditions for penetrative convection. The stationary convective patterns of different penetration depth, which originate after the basic throughflow has lost its stability, are revealed by Newton's method. The supercritical and subcritical nonlinear regimes are studied with increasing the supercriticality. All of the regimes enhance heat flux. The short-wave convective patterns localized mainly in the upper air layer appear over the upward basic throughflow. Their relative contribution to the total heat flux is much smaller than that of the basic flow. It decreases with increasing the Peclet number or relative air layer depth. The similar local patterns or patterns of a large wavelength can initiate over the downward basic throughflow. Their relative contribution to the total heat flux grows with increasing the parameters mentioned. The large-scale convective patterns which cover both air and porous layers and are typical for a strong downward throughflow and small air layer depth contribute into the total heat transfer more effectively than those located in the air layer only.

The paper studies convective heat and mass transport driven by a uniform internal energy source coupled with the solid fraction in different partial air-saturated porous domains. Each domain is bounded by the top and bottom impermeable thermally conductive surfaces. The linear stability analysis is performed and the disturbance equations are derived and numerically solved. The critical internal Darcy-Rayleigh number and wave number are found and compared for three distinct domains. The first domain is an air-porous-air one, where the heat-generating porous matrix is between the upper and lower air layers. In the second air-porous domain, the air layer overlays the porous medium. In the third porous-air domain, the air layer underlays the porous medium. The bimodal marginal stability curves and regime map with a demarcation line between the local and large-scale convective flows are obtained only for the APA and AP domains due to the division of each domain into the upper unstably stratified and lower stably stratified parts. The local convection cannot originate in the PA domain because the air layer belongs to the lower stably stratified part. A remarkable destabilizing effect of additional air layers has been revealed. For example, at the fixed solid fraction of 0.1, one achieves a 40-fold reduction of the critical Darcy-Rayleigh number in the APA domain by increasing the depth ratio from 0 to 0.5. It is by 14 times in the AP domain and is only by 3.5 times in the PA domain. The destabilizing effect enhances with increasing the solid fraction.
