Aiming at the defects of current thermal mass flow sensor, we developed a novel thermal gas mass flowmeter based on the principle of constant power, which consists of semiconductor sensors and a microcontroller as the core controller. The design plan is carried out on the basis of simple structure and reasonable cost, which maximizes accuracy and reliability of the flowmeter. The experimental results verify that the flow meter is running well and achieves the overall performance goals of the plan.

Impinging Flow

An experimental study of forced convection in impinging flow, using fluorocarbon FX3250 and a simulated electronic chip, was performed. A test section consisting of a 35 mm long, 1 mm wide slot nozzle in a 2 mm thick plate offset 2 mm from the heat source was used. The simulated chip array consisted of five foil strip (4 mm wide) heaters, positioned with the center strip directly beneath the slot nozzle. The velocity of the coolant was varied from 0.53 to 5 m/s, and the subcooling in the range from 2 to 21 K. The experiments were conducted focusing on two cases. First, only the center strip was heated. Second, all the heaters were energized, and the strip-by-strip variations of heat transfer were measured. The critical heat flux (CHF) on the center strip, determined by sensing the onset of oscillations and subsequent rapid rise of foil temperatures, was found considerably lower than those predicted by the existing correlations. It is pointed out that the thermal mass of the test heater could be an important factor for the CHF. The heat transfer behavior of other strips showed channel-flow or jet-impingement mode depending on the strip location and the coolant flow rate. [S1043-7398(00)00202-4]

Abstract Designing for climate resilience and carbon neutrality implies low-emission structures that double as thermal mass. In this study, the effect of using geometry to maximize natural surface convection on an internal thermal mass is investigated. Wood and concrete thermal masses are optimized for both instantaneous heat transfer and transient heat storage, and compared. It is found that the addition of optimally-sized fins can double or triple the convection coefficient at the interior surface, provided the thermal conductivity of the fins is sufficiently high. Doubling or tripling the surface heat transfer translates to an equivalent increase in dynamic energy storage, so long as the mass thickness, wall area, and vent openings are recalibrated to maintain thermal synchrony at the building-level.
