Increased prices for nonrenewable heating fuels (such as propane, heating oil, and natural gas) have residential and farm consumers seeking more sustainable solutions to their heating needs. Price increases among these fuels will remain a trend as a combination of decreased reserves and increased demand continues to limit supply (EIA, 2012). Pellets produced from abundant biomass sources—such a...

A spatiotemporal study of neutral gas temperature during the first 100 s of operation for a radio-frequency electrothermal plasma micro-thruster operating on nitrogen at 60 W and 1.5 Torr is performed to identify the heating mechanisms involved. Neutral gas temperature is estimated from rovibrational band fitting of the nitrogen second positive system. A set of baffles are used to restrict the ...

The heating of the lower solar corona is examined using numerical simulations and theoretical models of magnetohydrodynamic turbulence in open magnetic regions. A turbulent energy cascade to small length scales perpendicular to the mean magnetic field can be sustained by driving with low-frequency Alfvén waves reflected from mean density and magnetic field gradients. This mechanism deposits ene...

This paper describes fundamental characteristics of high frequency induction heating applied for Marine Fuel Oil (MFO) recovery system. The system is analyzed for an induction-heating load, related to operating frequency and input power. Frequency domain characteristics of load equivalent circuit parameters in induction heating are investigated to clarify an effective circuit design of the high...

Combustion-generated pollutants, principally those from solid-fuel including biomass and coal when cooking and heating, bring out a significant public health hazard in both developed and developing countries. Most of the existing studies addressing this issue focus on developing countries, and on exposure when cooking rather than heating. By using the Kentucky Homeplace Program data, this resea...

Manufacturing components of fiber-reinforced thermoplastics requires three steps: heating the matrix, forming and consolidation of the composite and terminal cooling the matrix. For the heating process a pre-determined temperature distribution through the layers and the thickness of the pre-consolidated sheets is recommended to enable forming mechanism. Thus, a design for the heating process fo...

Titanium and its alloys present high interests for technological applications due to their high corrosion resistance, mechanical properties and biocompatibility. In combination with these remarkable characteristics, some Ti applications require specific surface properties that can be imparted with suitable surface functionalizations of the TiO(2) oxide layer. The present work aims to study the ...

Non-collisional heating is an important phenomenon in low-pressure inductively coupled plasmas. In this paper, a self-consistent analytical model for non-collisional heating is developed which shows that non-collisional heating is a warm-electron effect that relies on a resonant interaction of electrons with the electromagnetic wave. Electrons with velocities comparable to the effective wave ph...

The present study investigates Joule heating in piezoresistive microcantilever sensors. Joule heating and thermal deflections are a major source of noise in such sensors. This work uses analytical and numerical techniques to characterise the Joule heating in 4-layer piezoresistive microcantilevers made of silicon and silicon dioxide substrates but with the same U-shaped silicon piezoresistor. A...

Treatment of sewage sludge by composting for the production of materials useful as a soil amendment is a feasible method of achieving both waste disposal and agricultural enhancement simultaneously。 However, the hygienic safety of the final products is an issue which requires resolution. This study was an investigation of the effects of heating patterns on the inactivation and regrowth potentia...
