Decreasing heating needed energy of building located in mountainous areas without any urban infrastructure of energy supply and services is one of the most important things to get thermal comfort. Accordingly, using building conditions based on different types of applicability and passive design strategies should be considered. Therefore, the objective of this study was to achieve the pro...

This paper focuses on the calculation of sizing ducting based cooling load requirements main office building following regulation airspeed using American Society Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) Computational Fluid Dynamics (CFD) simulations. The purpose this research is to validate turbulence that occurs in between manual calculations CFD From calculation, require...

This paper addresses the NOE path planning with incomplete information. We first define the path planning for NOE flight. Then we discuss how to divide the problem into several subproblems. For each of the subproblems, we propose a clear definition along with a brief description of the solutions to the subproblem.

the shape of a solar collector is an important factor in solar-to-thermal energy conversion. conical shape is one of the stationary and symmetric shapes that can be employed as a solar water heater. flow rate of working fluid on the solar collector has an important effect on the efficiency of the collector. the present study is an experimentally investigated of the performance of the solar coni...

In-duct ultraviolet germicidal irradiation (UVGI) systems treat moving air streams in heating, ventilation, and air-conditioning (HVAC) systems to inactivate airborne microorganisms. UVGI system performance depends on air temperature, velocity, cumulative operating time, variations in exposure time and other factors. Annual simulations of UVGI efficiency and space concentration that accounted f...
