This work is carried out to cool the air without letting air come in direct contact with coolant (water) and it was done to contain the humidity at low level inside the room which is to be cooled. To achieve this object a heat exchanger was introduced where indirect evaporative cooling takes place and to enhance air cooling a cooling tower and forced air draught on surface of heat exchanger was also added. This work had shown efficiency up to 72-89% and was able to bring the room temperature from 35℃ to 30℃.

Performance improvement of horizontal axis wind turbines by aerodynamic shape optimization including aeroealstic deformation

Renewable Energy, 2019

While potential-flow-based path planning approaches can help generate smooth paths in which cooperative aerial manipulators can avoid obstacles, they do not facilitate the consideration of velocity and curvature constraints. By contrast, while such constraints can be considered in the optimization approach, the approach often requires a heavy computational load. To overcome these drawbacks, we propose a simple approach based on curvature-constrained harmonic potential flow and a streamline-changing algorithm. We also handle the initial and final velocity problem by a smooth activation function, which is crucial for the tracking performance at the initial and final position. The proposed approach can be used to generate a smooth path for cooperative robots in real time. For the validation of the approach, the simulation results obtained with the proposed algorithm were compared with those acquired with an existing approach including dynamic movement primitives(DMPs). Furthermore, we performed load-carrying experiment using custom-made aerial manipulators. INDEX TERMS collision-free path planning, constraints, cooperative robots, multirotors, obstacle avoidance.

ABSTRACT-The Airfoil NACA 4415 of aerodynamics are mainly used as a wind turbine blades. So the selection of suitable angle of attack for the projected airfoil section involves in this. So the reason of this study is to investigate the behavior of NACA 4415 air foil at different operating condition. In this research CFD analysis has been done over NACA 4415 has been used in fluent 6.3.26. The CFD analysis has been done for angle of attack 12 0 , 14 0 , 16 0 and 18 0 at Reynolds Numbers 1000000 and 1500000. It was found as the angle of attack enhances, the coefficient of lift also enhances, but after 16 0 coefficient of lift started to reduces due to adverse pressure gradient at the trailing edge.

The geometry of PHE is one of the most important factors of rate of heat transfer and pressure drop .corrugation of plate inhances heat transfer due to increasing the turbulence in flow. Now a day PHE is being used widely in heating application, food industry, chemical industry, refrigeration industry, marine application and fresh water generation system from sea water. The objective of this paper is to review the effect of chevron angles and numerical investigation of dimensionless numbers. Further we shall design the PHE by using the solid work design software with chevron angles 45•, 61•, 63•, and 65• at constant dimensions. The rate of heat transfer coefficient, pressure drop dimensionless numbers like Nusselt, Prandtl and Reynolds numbers will be evaluated by using the Ansys simulation software.

RACs used for both heating as well as cooling purposes. RACs are available in different variants like 1 ton, 2 ton. In this paper, we will determine and find out exact or near about the temperature required for the selected room in which we put AC. This is important for some reasons. Undersized unit AC-This will not cool the room in more summer or hot weather season. Oversized unit AC-This will affect the body comfort by more cooling and also high money. So, by using calculation of room we will able to find out how much we have to give cooling or heating the room. For this we will save energy as well as money and the wastage of heat in the atmosphere.

Air contaminated with airborne viruses holds a substantial risk for household transmission. In this study, a novel thermal treatment system is modeled based on porous heating for the decontamination of airborne SARS-Cov-2. The model includes an air heating domain, insulated chamber, buffer tank and heat exchanger. The airborne SARS-Cov-2 is decontaminated when passing through a porous heat pipe and the insulated chamber for an anticipated dwelling period of more than 5 min at 105°C and further stored in a buffer tank for natural cooling. The obligatory decontaminated air is allowed in the residential space under ambient conditions passing through a heat exchanger. The numerical investigation of the porous pipe model at different L/D ratios with altered porosities aims to establish the best-performing porous domain. Besides this, the buffer tank is intended to maintain buffer storage of the treated air and significant natural cooling before passing to the heat exchanger. A solar PV module is proposed to meet the prerequisite energy requirements of the equipped devices.
