Heat transfer behavior of flat plate having 45° ellipsoidal dimpled surfaces

Forced Convection Heat Transfer Analysis through Dimpled Surfaces with Different Arrangements

“…Case 'c' dimple arrangement has better heat transfer enhancing capacity as compared to case 'a' & 'b' because of the increased flow rate in this type ofdimple arrangement. However, the Augmentation depends on the configuration [12].…”

“…It is also seen that most of the research is confined to flow in the channel i.e. Internal flow, with a very few studies on external flow [12]. So the main focus of this experimental work is to study the effect of circular dimples of various diameters under external laminar flow conditions…”

“…Fouling rate reduction b. Cost reduction c. weight reduction etc [11], however, much of the research work either experimental or numerical is on spherical dimples of uniform diameter [7,12]. It is also seen that most of the research is confined to flow in the channel i.e.…”

An Experimental Study of Heat Transfer Enhancement in the Circular Channel with Almond Shape Dimples

“…10 types of dimple arrangements and dimple intervals are studied. For the staggered arrangement of dimple it was found that 15.8% heat transfer was improved as compare to smooth channel [9]. M. Siddique et al made a review article for the recent advances in heat transfer enhancement [10].…”

Numerical Study on the Effect of Tube Rows on the Heat Transfer Characteristic of Dimpled Fin

“…J. Lee and K.-S. Lee [22] numerically studied the heat transfer performance of plate heat exchangers with dimples and protrusions, and based on the results, they gave the Nusselt number and friction factor correlations. Katkhaw et al [23] studied 10 types of dimple arrangements and dimple intervals on flat surfaces. The results showed that the heat transfer coefficients for dimpled surfaces of staggered arrangement were about 15.8% larger than that of smooth surface.…”
