For investigations of aerodynamic properties of helical instabilities in flowing fluids, an experimental rig is currently built [1]. It is intended on the one hand for visualisations of acoustically excited helical structures and on the other hand for model experiments with flows of cyclonal character. As the universal air source for both purposes, a blower is used for which no loading characte...

Infiltration is a common source of heat loss, especially in older homes. This case study focused on a 1924 house in the downtown Eugene area. Infiltration in this home is excessive due to a basement door left open at all times, a fireplace lacking a damper, and vents left over from a defunct oil heater. We hypothesized that sealing these large leaks would reduce the infiltration by 50%. A blowe...

The population of the world has been increasing gradually in recent times. Under excessive climatic conditions, plants can be grown with help Greenhouse. Green houses to maintain temperature within a limited range, used for cultivating out season. greenhouse control system is powered by ESP-WROOM 32 Wi-Fi Microcontroller and it consists humidity sensor, soil moisture PIR sensor MQ Gas monitor I...

Studies were conducted in 1994, 1995, and 1997 to determine the effect of assisting natural wind pollination using an air blower on yield and fruit characteristics of three tomato (Lycopersicon esculentum Mill.) cultivars. Tomato plants and flowers in the air blower–assisted treatment were vigorously vibrated at midday every other day on sunny days for 4 weeks. Plants and flowers in the control...

BACKGROUND AND OBJECTIVES Scalp psoriasis is a frustrating disorder whose treatments can all too often be cumbersome and ineffective. Our objective was to test a combination device involving the 308-nm excimer laser in tandem with a hair blower for treating scalp psoriasis. STUDY DESIGN/MATERIALS AND METHODS Adult subjects with scalp psoriasis unresponsive to class I topical steroids used in ...

a canola seed pneumatic conveyor was designed and constructed to convey canola seed at a 90 g/hr mass flow rate through a 58 mm diameter pipe. physical and aerodynamic properties of the canola seed that are critical to the design process were measured. system pressure drop, comprising air pressure drop and solid pressure drop and which is the most important aspect of pneumatic conveyor design, ...

The components of blower are composed of motor and impeller. Motors transform electric energy into mechanical rotating kinetic energy and this rotating kinetic energy produces flow through impeller. And thus blower is divided into motor and impeller. In actual development and study, the process of system formation is followed generally by joining the two independent research results. This study...

An experimental investigation has been carried out to study the turbulent flow heat transfer and to determine the pressure drop characteristics of air, flowing through a tube with insert. An insert of special geometry is used inside the tube. The test section is electrically heated, and air is allowed to flow as the working fluid through the tube by means of a blower. Air velocity, air inlet an...
