Numerical investigation of hydroelastic water-entry impact dynamics of AUVs

Traditional buildings throughout the globe provide instructive examples of sustainable solutions to building design problems. In recent years, researchers and architects have conducted different studies that represent the principles of Iran’s climate-responsive architecture. Yazd traditional buildings are examples of Iranian architecture that bear characteristics of environmentally friendly buildings. Thermal performance and comfort condition of these buildings in summer have been the matter of interest in recent studies. In this article, summer sections of Yazd traditional homes and their thermal behavior were studied. Yazd is located in hot and arid regions of Iran. EnergyPlus software program was used to investigate the thermal behavior of this house. To validate the developed model, a field study was carried out with lascar electronics data logger. The results reveal that internal temperature of summer sections in all seasons has less fluctuation than the outdoor temperature. Also, weather temperature in underground spaces is closer to the comfort temperature in comparison with spaces near to the ground floor. Therefore, to provide thermal comfort condition in these homes the least amount of non-renewable energy is needed.

An experimental and numerical investigation of Shovadan heating and cooling operation

A hydroelastic hybrid model is developed to simulate the fluid–structure interaction in water entry problems using the partitioned approach. The interactions between a flat plate and the water are modeled by a hydroelastic model using explicit and implicit couplings. Both couplings are unstable due to numerical instability associated with the fluid added mass. To overcome the instability, an extended Wagner’s model is combined with the hydroelastic model, and a hybrid model is developed. The extended Wagner’s model is the extension of the classical Wagner’s model that is used to estimate the fluid inertial, damping, and restoring forces of a flexible plate within the potential flow theory. The fluid flow is described by the unsteady Reynolds averaged Navier–Stokes equations in the hydroelastic model and hybrid model. The longitudinal bending of the plate is approximated by the strips in all models. The hybrid model is verified and validated by comparing the available computational and semi-analytical results of the vertical and oblique water entries for the plate with different boundary conditions. The results show that the hybrid model is stable, accurate, and simple to implement. This two-dimensional model can be generalized to the third dimension and applied for more complex structures.
