Conceptual design of an example heat accumulator - Heat exchange 1. The dimensionless solidification time of a phase change material is determined by: Stefan number Fourier numberThe product of Stefan number and Fourier numberBiot number2. TWhen calculating the parameters of a heat accumulator, the Biot number is calculated, which:Increases with the thickness of the heat accumulator plateDecreases with the thickness of the heat accumulator plateThe thickness of the plate does not matter3. In what units is the heat of phase transformation measured?in J/kgin K/min K/kg4. The parameter that determines this ratio of phase transformation heat to capacitive heat is called:Stefan numberFourier numberNusselt number5.In heat accumulators, PCM materials are characterized by the fact that Stefan numbers take values: Greater than unityLess than unity Very large values 6. Heat flux density has a unit:W/m2W/m3W/mall of the above answers7. Conduction of heat is described by:Fourier's equationNewton's cooling lawOther...You will receive the evaluation as an e-mailE-Mail !
