It was found that the heat transfer coefficient at the bottom of the pipe is up to three times higher than that at the top, and becomes more uniform around the pipe for higher air flow-rates. Correlations on local and average Nusselt number were obtained and compared to results reported ...
Air -10 to 100 W/m2K Water -500 to 10 000 W/m2K Multi-layered Walls - Heat Transfer Calculator This calculator can be use to calculate the overall heat transfer coefficient and the heat transfer through a multi-layered wall. The calculator is generic and can be used for metric or imper...
A local heat transfer coefficient (HTC) has been determined for six cases of vertical plates cooling by the water-air assisted sprays. Full cone 60掳 nozzle operating under pressure of 0.1, 0.25 and 0.4 MPa has been employed. The plates have been made from the Inconel alloy and stainless ...
In order to increase the heat transfer coefficient of the fluid outside the tube, a number of baffles are usually installed in the housing. Food grade stainless steel sanitary shell and tube heat exchanger 1. Tuber exchanger is the equipment that can transfer cert...
The paper presents the method and results of determination of heat transfer coefficient for air-atomized water spray cooling with consideration of infrastr... M Aposto,P Skubisz,H Adrian - 《Materials》 被引量: 0发表: 2022年 Heat Transfer Behavior During Water Spray Quenching of 7xxx Aluminum...
Condensing Water Vapor: 5.000 - 100.000 (W/(m2K)) Heat Exchanger Heat Transfer Coefficients Convective Heat Transfer Coefficient for Air The convective heat transfer coefficient forairflow can be approximated to hc= 10.45 - v + 10 v1/2(2) ...
The intention of this work was to study the effect of cover materials on heat and mass transfer coefficient and hence productivity of the still. Two plasti... MK Phadatare,SK Verma - 《Desalination & Water Treatment》 被引量: 20发表: 2009年 Numerical Study of Heat and Mass Transfer MHD ...
air near the surface and the fall of the cooler (and thus heavier) air to fill its place. Heat transfer between the block and the surrounding air is by conduction if the temperature difference between the air and the block is not large enough to overcome the resistance of air to movement...
The effect of tube diameter on the air-side performance is significant. Larger tube diameter not only gives rise to lower heat transfer coefficient but ... A Nuntaphan,T Kiatsiriroat,CC Wang - 《Applied Thermal Engineering》 被引量: 43发表: 2005年 Experiments on the Dehumidification Performance...
(2)) is applied to determine the heat transfer coefficient (Farinu and Baik, 2007, 2008; Sandhu et al., 2016). (2)hA(To−Ts)=Q1+Q2 where Q1 is the energy consumed for water evaporation and Q2 is the energy used to heat up the product, so Eq. (2) can be rewritten as Eq. ...
